摘　　要：本文以越城区曲屯1号地块3标段项目为研究对象,采用三维数值模拟进行建模分析,研究了基坑坑底加固体在刚度、宽度以及深度不同时对建筑物沉降的影响。结果表明采用150Mpa的刚度以及5.5m的深度进行满堂加固更具优势。Taking the project of section 3 of Qutun No.1 block in Yuecheng District as the research object,the relationship between building settlement and foundation pit bottom reinforcement under different stiffness,width and depth conditions was studied by means of three-dimensional numerical simulation.The results show that it is more advantageous to adopt 150 Mpa stiffness and 5.5 m depth for full reinforcement.
