FINITE ELEMENT NUMERICAL SIMULATION OF DEEP FOUNDATION PIT EXCAVATION SUPPORTED BY FROZEN SOIL WALL WITH NONHOMOGENEOUS TEMPERATURE DISTRIBUTION
非均匀温度分布冻土墙围护深基坑开挖的有限元数值模拟

The deformation of deep foundation pit is analyzed by using the subsection approximation of finite element numerical simulation. The nonhomogeneous temperature distribution is considered by the analysis of temperature of frozen soil wall,and the results of nonhomogeneous temperature distribution are compared with these of the homogeneous ones. Many significant conclusions are obtained and some valuable advice for construction and design is given.
