What is the holding layer in the building, and what is the holding layer?

In the design of civil engineering structures, the soil layer that directly bears the load of the foundation is called the bearing layer when designing the foundation.

In the calculation of soil mechanics, the pressure on the bearing layer is constantly decreasing, and the pressure is negligible after reaching a certain depth, and the specific depth is only known through calculation.

This part of the pressure is called the bearing layer, and the part below the bearing layer is called the lower layer. In other words, depending on the load, the bearing layer and the substratum are different.

Extended information: The bearing layer is subjected to the greatest stress, which directly affects the safety of the building. Therefore, in the design, the strength of the entire foundation, including this formation, should be checked and, if necessary, its settlement.

The load borne by the bearing layer foundation gradually decreases with the deepening of the soil depth, and the load borne by the soil layer after reaching a certain depth is negligible. At this time, we call the soil below this layer the underlayment. Although the load on the lower layer is negligible, if the lower layer is weak, it needs to be dealt with.

For example, if the substratum is silty, then the bearing capacity of the substratum should be calculated. If the calculation is not sustainable, then the foundation treatment or pile design should be considered.

In the design of civil engineering structures, the soil layer that directly bears the foundation load is called the bearing layer in the design of the foundation.

Within the stress range of the foundation, the soil layer below the bearing layer is called the substratum, and the highly compressible soil layer whose bearing capacity is significantly lower than the bearing layer is called the weak substratum.

The so-called bearing layer of pile foundation is the rock and soil layer that carries the pile head part of the pile foundation, and the rock and soil layer with relatively large bearing capacity is generally selected as the bearing layer (avoiding the relatively weak soft base, strong weathering layer and less stable soil layer).

The bearing layer is the soil layer that requires the soil layer to reach the force that the design can bear when the foundation stress calculation is carried out, and the soil layer or rock layer that bears the load of the whole building is the bearing layer.

It directly bears the load from the foundation and spreads the load to the earth's crust through a sufficient thickness of soil, which is called the bearing layer.

Hello, I will solve your doubts for you below, I hope it can help you. The bearing layer actually refers to the soil layer used to bear the foundation load when the foundation is driven to the foundation in the civil engineering structure. The construction of this level of engineering also needs to go through precise calculations, and the bearing layer created by workers without any construction experience will also have certain safety hazards, and will also have a certain impact on the overall structure and stability of the house.

I really hope I can help you, and I wish you happiness every day!

In the design of the foundation, the soil layer that directly bears the foundation load is called the bearing layer. In the calculation of soil mechanics, the pressure on the bearing layer is continuously reduced, and the pressure can be ignored after a certain depth, and the specific depth is known through calculation.

The part that is under pressure is called the holding layer, and the part below the holding layer is called the lower layer. In other words, depending on the load, the bearing layer and the substratum are also different.

Method for determining the bearing layer of the foundation:

The geological report of the geological exploration department provides the characteristic values and suggestions of the bearing capacity of each layer of the foundation, which can be determined by the structural engineer according to the load of the project at hand, the use function and importance of the project, and the comprehensive consideration of technology, economy, and construction capacity.

Extended Materials. Requirements for the bearing layer of the foundation:

1. Strength: The foundation should have sufficient bearing capacity;

2. Deformation: The settlement of the foundation needs to be controlled within a certain range, and secondly, the settlement difference of the foundation in different parts should not be too large, otherwise the upper part of the building will crack and deform;

3. Stability: The foundation should have the ability to prevent overturning and instability.

4. Pressure: Appropriate pressure.

The bearing layer is the soil layer that directly bears the load of the foundation.

In the calculation of soil mechanics, the pressure on the bearing layer is continuously reduced, and the pressure can be ignored after a certain depth, and the specific depth is only known through calculation. This part of the pressure is called the holding layer.

The expression of the bearing layer is used in the design of civil engineering structures and in the design of foundations. The determination of the front shed of the bearing layer can provide the characteristic values and suggestions of the bearing capacity of each layer of the foundation according to the geological report of the geological exploration department. The structural engineer can determine the bearing layer according to the load of the project, the use function and importance of the project, and comprehensively consider the technology, economy, and construction capacity.
