超深大基坑支护设计原理及三维有限元数值分析

随着我国经济的高速发展，城市可以利用的空间越来越少，这就要求更多的建筑开始向地下发展，深基坑支护在城市建设中频繁使用，如何保证深基坑的安全性、合理性已经成为深基坑设计中的重要问题。本文结合工程实例，利用岩土计算软件理正深基坑7.0和有限元分析软件Midas-GTS对基坑的安全性进行分析，其支护结构设计和三维有限元分析结果其分析结果可为优化设计和施工提供有益参考，为类似工程提供借鉴。

Super Deep Foundation Pit Supporting Design Principle and the Three-dimensional Finite Element Numerical Analysis

Along with the rapid development of economy in our country, the space that a city can take advan. tage of becomes less and less. Thus, it is necessary to develop underground buildings, using deep foundation pit supporting. How to guarantee the security and the rationality of the deep foundation pit has become the important problem in the design of deep foundation pit. Based on the engineering example and using the calculation software of geotechnical principle of deep foundation pit and the finite element analysis software Midas GTS-7.0 to analyze the security of foundation pit, its analysis results can provide reference for optimization design and construction of similar projects.
