| Abstract: | In the area with rich groundwater,the floating accidents of basement are more frequent during construction.Taking the floating accident of a basement as an example,the occurrence and development of the floating accident and the subsequent process of additional uplift pile and structural repair are analyzed in detail.This paper analyzes the key and difficult points in the process of comprehensive application of anchor static pressure pile reinforcement and joist column replacement structure repair technology,and observes the whole process of building settlement,which can provide reference for similar projects. |
