What is the practical significance of slope stabilization? What are the factors that affect the stab

Natural slopes in mountainous areas, rivers.

The bank slope and the artificial slope formed by leveling the site and excavating the foundation pit in the construction project, due to the influence of some external unfavorable factors, causes the slope to slide locally and loses stability, and the collapse of the slope often causes serious engineering accidents, and endangers personal safety.

Therefore, the appropriate slope section should be selected, reasonable construction methods should be adopted, and the stability of the slope should be checked and appropriate engineering measures should be taken if necessary, so as to ensure the stability of the slope. The purpose of reducing the amount of earthwork filled, shortening the construction period and saving safety and saving.

The factors that affect the stability of the slope are generally as follows:

1) The soil slope force changes. For example, due to the stacking of materials on the top of the slope or the construction of buildings to load the top of the slope, or due to the vibration caused by piling, vehicle driving, blasting, etc., the original equilibrium state has been changed.

2) The reduction of the shear strength of the soil. For example, the water content in the soil.

or an increase in pore water pressure.

3) The role of hydrostatic pressure. For example, rainwater or surface water flows into vertical cracks in the soil slope, creating lateral pressure on the soil slope and thus promoting the sliding of the puncture.

4) The seepage of groundwater in the slope such as earth dam or foundation pit is often an important factor of slope instability, because the seepage will cause hydrodynamics, and the fine particles in the soil will pass through the pores between the coarse particles and be carried away by the seepage, so that the compactness of the soil will decrease.

5) The height of the soil slope or the foot of the slope increases due to the excavation of the foot of the slope.

Practical Significance of Soil Slope Stabilization:

Soil slope stability can ensure road safety, pedestrian safety, and building safety. The instability of soil slope will make the geological body prone to disasters such as creeping landslides and debris flows under the action of gravity geology. Soil slope stability is mainly to study whether the general slope or earth-rock dam or embankment will have undesirable geological phenomena such as sliding instability in the case of load (or no load).

The factors that affect the stability of soil slopes are:

Claysiness, water, slope, vegetation of the soil, in addition to artificial actions (such as artificial slope fixation measures), geological processes (**, etc.).

Causes of slope instability.

1. Changes in the force on the soil slope: for example, the load on the top of the slope is due to the stacking of materials or the construction of buildings on the top of the soil slope. Or due to the vibration caused by piling vibration, vehicle driving, blasting, etc., the original equilibrium state of the soil slope has been changed;

2. Reduction of soil shear strength: for example, the increase of water content or superhydrostatic pressure in the soil;

3. The role of hydrostatic pressure: for example, rainwater or ground water flows into the vertical cracks in the soil slope, which produces lateral pressure on the soil slope, thereby promoting the sliding of the soil slope. Therefore, cracks in cohesive soil slopes are often an unfavorable factor for soil slope stability and one of the precursors of landslides.

1. The force on the soil slope changes. Loads on the top of the slope due to the stacking of materials or the construction of buildings on top of the slope. Or due to the vibration caused by piling vibration, vehicle driving, blasting, etc., the original equilibrium state of the soil slope has been changed;

2. The reduction of soil shear strength. Such as the increase in water content or superhydrostatic pressure in the soil.

3) The role of hydrostatic pressure. If rainwater or surface water flows into the vertical cracks in the soil slope, it will exert lateral pressure on the soil slope, thereby promoting the soil slope to slide. Therefore, cracks in cohesive soil slopes are often an unfavorable factor for soil slope stability.

Measures to prevent instability:

1. It is not suitable for construction in rainy seasons.

2. Follow the construction procedures of reinforcement and treatment first, and then excavation.

3. Do a good job of surface and underground drainage facilities first, and divert surface water and groundwater.

4. The stability of the soil slope is poor, and it is strictly forbidden to dump soil or pile materials on the top of the slope.

5. The top-down excavation sequence must be followed, and it is strictly forbidden to cut off the foot of the slope first; If the foot of the slope is cut first, the upper soil will lose its support and the soil slope instability will be easily generated.

6. After the slope excavation is completed, the soil slope slope protection is carried out by means of plastic film covering, cement mortar plastering, hanging net plastering or spraying, which can effectively prevent soil slope instability.

(1) The influence of the structure at the bottom of the slope on the stability of the slope. The stability of the bottom breaking directly affects the stability of the whole mountain, and (2) the influence of external forces on the slope. For example:

blasting, water pressure and other natural and thought factors, which lead to slope failure. (3) The influence of slope shape on slope stability. For example, rivers, reservoirs and lakes.

(1) the type of soil influence; (2) Affected by the degree of soil humidification, the soil contains more water, and the slope is easy to be unstable; (3) the influence of climate makes the soil soft; (4) The influence of the external force of the additional load on the slope.

It should be composed of three aspects: one is the soil quality (soil particles, categories), the second is the height of excavation and filling, the third is external factors, especially the moisture content, as well as the time of the slope retention, the drainage situation, the earthwork construction plan, whether there is soil on the slope, etc.

Soil quality, cut-and-fill height, slope retention time, drainage, upper slope load, construction method, etc.

Summary. Hello, 1.Slope height:

The higher the slope height, the easier it is for the sliding surface to expand, resulting in poor slope stability. 2.Slope angle: The stability of non-cohesive soil is greatly affected by slope angle, and the larger the slope angle, the worse the slope stability; 3.

Slope: The slope shape is irregular, which will increase the soil and hydraulic forces and reduce the stability of the slope; 4.Soil Structure:

The looser the non-cohesive soil structure, the worse the slope stability. 5.Soil characteristics: the higher the density and bulk density of non-cohesive soil, the better the slope stability; 6.

Water level: If the soil is full of seepage, the friction between the soil and the sliding surface will be reduced, which may damage the slope stability; 7.Geological processes:

Cracks in non-cohesive soils affect stability. Cracks are easy to greatly reduce the friction between the slope surface and the sliding surface, thereby destroying the slope stability.

Which of the following factors is the main factor affecting the stability of non-cohesive soil slope, the first one, slope height, slope angle, slope surface, hurry up and run out of time.

The factors that affect the stability of the slope are generally as follows:

1) Changes in the force of the soil slope, such as the load on the top of the slope due to the stacking of materials or the construction of buildings on the top of the slope, or the shaking caused by piling, vehicle driving, blasting, etc., changes the original equilibrium state.

2) The decrease in the shear strength of the soil, such as the increase in the water content or pore water pressure in the soil.

3) The effect of hydrostatic pressure, such as rainwater or vertical cracks flowing into the soil slope on the ground, produces lateral pressure on the soil slope, thereby promoting the sliding of the soil slope.

4) The seepage of groundwater in the slope such as the earth dam or Jihuiliang pit is often an important factor of slope instability, because the seepage will cause hydrodynamic force, and the fine particles in the soil will pass through the pores between the coarse particles and be carried away by the seepage, so that the density of the soil will decrease.

5) The height or angle of the soil slope increases due to the excavation at the foot of the slope.

The natural slope of the mountainous area, the bank slope of the river and the artificial slope bending surplus formed by leveling the site and excavating the foundation pit in the construction project, due to the influence of some external unfavorable factors, causes the local soil of the slope to slide and loses stability, the collapse of the slope often causes serious engineering accidents, and endangers personal safety, therefore, the appropriate slope section should be selected, a reasonable construction method is adopted, and the stability of the slope should be checked if necessary and appropriate engineering measures are taken to ensure the stability of the soil slope. The purpose of reducing the amount of earthwork filled, shortening the construction period and saving safety and saving.

1. The external load action or environmental changes of the soil slope lead to the increase of the internal shear stress of the soil, such as the excavation of the cutting or foundation pit, the increase of the upper filling load in the construction of the embankment, the increase of soil saturation caused by rainfall, and the penetration of water inside the soil. Excessive load at the top of the slope or dynamic load caused by **, piling, etc.;

2. Due to the influence of various external factors, the shear strength of the soil is reduced, which promotes the instability and breaking of the soil slope, such as the increase of water pressure in air raids, the dry cracking, freeze-thaw caused by climate change, the softening of the clay interlayer due to the invasion of rain, and the reduction of soil strength caused by the creep of cohesive soil.
