软土地区基坑围护结构设计的实践

The Practice for the Construction Design of Foundation Pits Retaining Wall on the Soft Subgrade Area

上海属软土地区 ,工程地质条件较差 ,由于城市建设用地的控制和周围建筑、道路、地下管线等环境的影响 ,作为地下工程基坑开挖的临时性围护结构的设计研究成为非常重要的课题 :必须确保基坑自身的安全和对周边建筑、道路、地下管网保护 ,同时也必须做到经济合理、施工方便。

Shanghai belongs to the soft subgrade area. As an international metropolis, land resource is particularly precious! Because of the land controlling for city construction and the influence on the surrounding buildings, roads, underground tube lines, it's very important to study the construction design of temporary retaining wall of foundation pits. The construction design must fulfill the safety of foundation pit itself and the protection to the surrounding buildings, roads, underground tube line net. In the meantime, it must also attain the reasonable economy, convenient construction. This paper is based on a real practice.
