软土地区复杂环境下深大基坑设计与施工

Foundation pit design and construction under complex environment in soft soil area

随着我国城市建设用地、空间的日趋紧张,很多建筑受周围环境的制约,只能向地下发展。因此,对地下基坑围护结构的分析、计算也越来越为业内人士所重视。此文结合上海铁路局某工程地下围护结构的工程实例,介绍软土地基情况下基坑围护结构设计方案的设计思路、设计方法等方面的内容。

With chinag urban construction lands and urban spaces being increasingly strained, many buildings have to exploring spaces under the ground compelled by environmental restriction. Thus, analysis and calculation to foundation pit support envelope entails more and more attentions from insiders. Combined with engineering examples of a foundation pit support envelope of Shanghai Railway Administration, this paper introduces design ideas and methods of foundation pit support envelope under complex environment in soft soil area
