摘　　要：基坑开挖和上部结构同时施工的情况越来越多,但是其过程受力特性并不十分清楚。通过ABAQUS有限元软件分析基坑分块分层开挖和上部结构同时施工过程中基坑和上部结构的受力与变形。该考虑空间效应的分析方法十分接近现场施工情形,能准确模拟施工过程中受力状况。The situation that simultaneous excavation of foundation excavation and construction of superstructure is more and more,but its stress characteristics is not clear. while block excavation and superstructure are constructed at the same time,their force and deformation can be analyzed with the help of finite element software ABAQUS. The analysis way that considers space effect is close to the site construction,and it can accurately simulate stress state during construction.
