某大厚度湿陷性黄土场地既有建筑不均匀沉降地基基础检测鉴定与加固设计

In this paper, based on the detection, identification and reinforcement design of a school catering building located in the large thickness collapsible loess site, the detection, identification and reinforcement design of existing buildings in the large thickness collapsible loess site after uneven settlement are studied. For the existing buildings with uneven settlement due to water immersion in collapsible loess site, a series of engineering practices, such as detection and identification, reinforcement design, and design service, are summarized. The calculation method of pit type static pressure steel pipe pile reinforcement for the foundation of existing buildings in collapsible loess site is summarized. The reliability of reinforcement and the effectiveness of local jacking correction are summarized, and some conclusions are concluded.It can provide reference for similar projects in the future.
