Judgment of engineering importance level Code for Geotechnical Engineering Investigation 3 1 class

If one of the importance levels of the site, foundation, and project is level 1, the survey level is Class A. The basement of your house is 10m, and it is estimated that it should be classified as a first-class building, although you have not said the general situation of the site and foundation, it can basically be regarded as a geotechnical engineering grade A investigation.

Law of the People's Republic of China on Earthquake Prevention and Disaster Reduction (Revision) (adopted at the 29th Session of the Standing Committee of the Eighth National People's Congress on December 29, 1997 and amended at the 6th Session of the Standing Committee of the 11th National People's Congress on December 27, 2008).

According to the Disaster Reduction Law, major construction projects refer to projects that have great value or impact on society (such as buildings and structures of major cultural relics value and commemorative significance). The construction projects that may cause serious secondary disasters refer to the construction projects that may cause floods, fires, large leakage of highly toxic or highly corrosive substances and other serious secondary disasters after being damaged, including reservoirs, dams, embankments and facilities for oil storage, gas storage, storage of flammable, explosive, highly toxic or highly corrosive substances, and other construction projects that may cause serious secondary disasters. Nuclear power plants and nuclear facilities projects, serious secondary disasters that may cause radioactive contamination after being damaged must be carefully evaluated for safety, and strict seismic fortification must be carried out in accordance with the law.

Classification Standard for Seismic Fortification of Construction Engineering GB50223-2004

3 0 1 The classification of seismic fortification of buildings should be determined according to the comprehensive analysis of the following factors:

1. The size of the personnel, direct and indirect economic losses and social impacts caused by building damage.

2. The size and status of the city, the characteristics of the industry, and the scale of industrial and mining enterprises.

3. After the failure of the building use function, the scope of impact on the overall situation, the impact of earthquake relief and the difficulty of recovery.

4. When the importance of each section of the building is significantly different, the seismic fortification category can be divided according to the section.

5. The same building in different industries, when the status and the consequences and impacts of the damage are different, the seismic fortification category can be different.

Note: Sections refer to the structural units separated by seismic joints, the parts with different functions in the plane, or the parts with different functions from the top and bottom.

3 0 2 Buildings should be divided into four seismic fortification categories of Category C and Category D according to the importance of their use function.

Class A buildings should belong to major construction projects and buildings that may have serious secondary disasters when they occur, Class B buildings should belong to buildings that cannot be interrupted or need to be restored as soon as possible, Class C buildings should belong to general buildings other than Class A, B and D, and Class D buildings should belong to earthquake-resistant secondary buildings.

3 0 4 This standard only lists examples of Class A, B and D buildings and a small number of Class C buildings in major industries; Buildings with similar functions and scales can be classified into seismic fortification categories according to similar building examples. Buildings not listed in this standard should be classified as Class C buildings. Although the comprehensive building and the logistics building belong to the floors in the hospital, it depends on the location of the hospital, (whether it is county-level or prefecture-level or municipal), the ward building (inpatient department) and medical technology building of the hospital belong to Class A or Class B, and the logistics building may be a Class C building; For details, please refer to the "Classification Standard for Seismic Fortification of Construction Projects" GB50223-2004.

It is comprehensively assessed by three categories: engineering importance level, site complexity level, and foundation complexity level.

For details, please refer to the geotechnical investigation specifications.

You're talking about terrain, right? It is recommended that you go to the geotechnical engineering survey specification, which is clearly written.

The one or two sentences you asked are really not clear, and I suggest you go and look at the specification.
