What are the types of venues? The category of the building site

<> are divided into four categories, which are , .

1. Quasi-site: rocky, compact gravel soil.

2. Quasi-site: medium-density, loose gravel soil, compact, medium-density gravel, coarse and medium-sand; 150kpa of cohesive soil.

3. Class site: loose gravel, coarse and medium sand, dense and medium dense fine silt of Qidu Qiaochun, cohesive soil with a allowable bearing capacity of 150kpa and 130kpa fill.

4. Quasi-site: silt-sensitive and argillaceous soil, loose fine silt, newly deposited clayey soil; Allowable bearing capacity of foundation soil.

<> building site categories are divided into four categories, which are Min Jing Nai Yes and Class .

1. Quasi-site: rocky, compact gravel soil.

2. Quasi-site: medium-density, loose gravel soil, bridge-spring compact, medium-density gravel, coarse and medium sand; 150kpa of cohesive soil.

3. Class site: loose gravel, coarse and medium sand, compact, medium-density fine silt, cohesive soil with a allowable bearing capacity of 150kpa and 130kpa of fill.

4. Quasi-site: silty soil, loose fine powder manuscript sand, newly deposited clayey soil; Allowable bearing capacity of foundation soil.

There are 4 types of venues, which are: class, class, class, class. Among them, classes are divided into i0 and i1.

The classification of the site category is based on factors such as the thickness of the overburden and the soil layer of the building site, which can be referred to the Code for Seismic Design of Buildings. The following is a specific introduction to the "venue category", interested friends can continue to read and understand.

1. Type 1: site-like soil, that is, rocky and compact gravel soil. Gravel soil is a kind of mixed soil, that is, gravel and soil particles, which is extensive, high strength, small deformation and good permeability, and is mostly used in water conservancy projects, railway projects, foundation projects, etc.

2. Type 2: Soil-like soil, including (1) medium-dense and loose gravel soil. (2) Dense and medium-dense gravel sand, coarse sand, and medium sand. (3) The allowable bearing capacity of the foundation soil [0]> 150kpa of cohesive soil.

3. Type 3: Soil-like soil, including (1) loose gravel, coarse sand, and medium sand. (2) Dense and medium-dense fine sand and silt sand. (3) The allowable bearing capacity of the foundation soil is [0] 150kpa cohesive soil and [0] 130kpa fill.

4. Type 4: Soil-like soil, including (1) silty soil, loose fine sand and silt sand. (2) Newly deposited cohesive soils. (3) The allowable bearing capacity of the base soil of Qinsui [0]< 130kpa.

<> site category can be found in the Code for Seismic Design of Buildings. Code for Seismic Design of Buildings was published in 2002 by the National Standard Seismic Code Management Group.

By reading the above "venue category" and "what specification to check the venue category", I hope to provide you with reference. For more information on the types of venues, please refer to the other relevant information.

1. The second category of the site category is the site soil. Soil-like: medium-dense, loose, hard gravel soil.

dense, medium-dense gravel, coarse, medium sand; The foundation soil has a cohesive soil with a allowable bearing capacity of 250kpa, which is generally used for highways and buildings.

2. According to the thickness of the overburden of the construction site and the equivalent shear wave velocity of the soil layer, the classification of the construction site is made according to the relevant regulations. It is used to reflect the comprehensive amplification effect of different site conditions on bedrock vibration. The categories of the site are divided into four categories, namely , , of which the classes are divided into two subcategories: 0 and 1.

For specific classification provisions, please refer to the Code for Seismic Design of Buildings

provisions.

First, the main body of classification is different: the main body of site soil type classification is the soil layer where the structure is located; The main body of the building site category classification is the building site.

Second, the classification criteria are different: the site soil type is classified according to the nature of the soil layer; The category of building site is the classification of construction site according to relevant regulations according to factors such as the thickness of the covering layer of the building site and the soil stiffness of the site.

Third, the content is different: the type of site soil is divided into class site soil, class site soil, class site soil, class site soil; The classification of the building site is based on the equivalent shear wave velocity of the soil layer and the thickness of the site cover. At the same time, according to"Equivalent shear wave velocity of the soil layer"with"Thickness of the site Kaina covering"The two-parameter parameter is divided into four categories: class, class, class, and class (where class can be divided into two subclasses, o and 1).
