摘要
深基坑支护设计,不仅要保证基坑内的正常作业,而且要防止基坑及坑外土体移动,确保基坑附近建筑物、道路、管线的正常使用。在众多围护方法中,SMW工法以其适用性强、围护成本低、施工周期短而倍受关注。本文结合工程实践,在设计与施工的关键技术方面,对大直径SMW工法在上海软土地基深基坑支护中的应用进行一些探讨。
The design of the deep foundation pit is not only to guarantee regular production during the construction,but also to prevent the movement of the foundation and the movement of the surrounding soil. The design must take into account the functionality of the nearby buildings, roads and pipelines. Out of the many methods used for confined support for the foundation pit, the SMW engineering method is one of the most popular ones to date due to its compatibility, low production cost and short construction period. This article research as on the implementation of the SMW engineering method, which is used in a real project for the deep foundation pit on soft soil ground in Shanghai. It is specially focused on the two major aspects of the SMW technique, namely the design and the construction.
