通过对某地铁工程围护结构变更设计介绍,详细阐述了SMW工法围护结构的设计方法及计算过程,并提出该围护结构设计与施工中存在的一些主要问题,总结了设计施工效果,该工法凭借其施工简便、造价较低的优势在地下工程的建设中得到更大范围的推广。
Through the design introduction of the modification of the envelope structure of a metro project, the design method and calculation process of the SMW envelope method are expounded in detail. Some main problems in the design and construction of the envelope structure are proposed, and the design and construction results are summarized. With its construction method is simple, low cost advantages in the construction of underground projects to be a wider range of promotion.
