Abstract
Based on the construction practice of a foundation pit support project,this paper analyzes the deformation of the support structure and the settlement of the surrounding terrain.The results show that the lateral displacement of continuous wall has a triangular change with the excavation depth,and a positive and negative correlation with the excavation depth.The overall peripheral settlement and the distance from the foundation pit showed a first positive and then negative correlation,which showed the settlement trend of groove shape.There is a positive correlation between the settlement of high-rise buildings and the excavation depth of foundation pit.In this project,the maximum lateral displacement of the foundation pit continuous wall is about 15mm;The settlement of the largest adjacent high-rise building reaches 5mm,which fully meets the requirements of the code.关键词
