Abstract

In order to make full use of the limited land resources, it is an inevitable trend of architectural development to develop underground. With the rapid development of urban construction and the rise of subway, underground spaces are constantly being developed, such as underground parking lots, underground shopping malls, underground warehouses, underground substations and a variety of underground civil and industrial facilities, resulting in a large number of deep foundation pit projects. The construction of deep foundation pit has the characteristics of high risk coefficient, high technical requirements and many influencing factors. If the design of supporting structure is unreasonable or the construction process is not strictly controlled, it will cause hidden dangers of quality and safety, which is not conducive to the smooth implementation of the project. In order to avoid possible uncertainties, it is necessary to adopt a more efficient and safe construction design scheme to provide effective guarantee for smooth construction. This paper expounds the problems encountered in the design and construction of deep foundation pit support, and puts forward the design strategy of deep foundation pit support scheme based on fuzzy grey correlation projection method.
