Code and description of building foundation design

In a building project, the most important thing is the foundation construction. The quality of foundation construction is directly related to the height of the whole building, and in order to make the building reach a certain height, there are some special requirements for foundation. Therefore, everyone engaged in engineering needs to know the Code for Design of Building Foundation. The design of foundation also includes earthquake-proof design, which represents the safety of human life. So what should we pay attention to when designing the foundation? First of all, let's understand the relevant contents of the Code for Design of Building Foundations.

These aspects are all involved in the Code for Design of Building Foundations. For the introduction of some terms and symbols, some basic provisions of foundation design, some classification and index problems of rocks, some calculation of foundation, introduction of mountain foundation, introduction of soft foundation, basic knowledge of design, some basic engineering and inspection of foundation, the rest are some supplementary explanations of foundation geology.

There are many contents in Code for Design of Building Foundations. Bian Xiao will give you a brief introduction here.

The foundation of each building is graded, which is roughly divided into three grades: A, B and C. For important industrial and residential buildings, buildings with complex geological conditions, buildings with more than ten floors and buildings with high environmental requirements, designer-grade foundations are needed, while for buildings with less than seven floors, the geological conditions are relatively simple, and buildings without deep foundation pits can design C-grade foundations, while other buildings can design B-grade foundations.

There are many kinds of fill in the foundation, such as sand, rock, silt, gravel soil and so on. However, the hardness of each soil is different and the characteristics of each soil after excavation are different, so it is necessary to know all aspects of the soil in advance and have dealt with some excavation problems.

Before foundation construction, some tests are needed to ensure all aspects of foundation, and the shear strength, allowable index of load test and compressive index of foundation need to be measured. Relevant data should be provided after the test to facilitate the next construction.

The depth of the foundation should be determined according to the height and use of the building, not only according to the strength it needs to bear, but also according to the characteristics of its geological water quality. If the building has special requirements, it needs to be dug deep enough when necessary to avoid problems such as soil quality.

There are many contents in Code for Design of Building Foundation. If you really need these materials, I suggest you buy relevant books directly to facilitate your understanding of it! '
