SMW工法桩在天津地铁基坑围护结构中的应用

Application of SMW Method in Tianjin Subway Pile Foundation Pit Structure

基坑工程主要包括基坑支护体系设计与施工和土方开挖,是一项综合性很强的系统工程,不仅涉及基坑支护结构与土体的相互作用问题,还涉及强度、变形与稳定问题。天津某地铁基坑围护结构,基坑主体以地连墙结构形式为主,附属结构为SMW工法桩形式,对天津地铁基坑围护结构中SMW工法桩的施工工艺和质量控制进行分析。

The Foundation works mainly comprise the Foundation Bracing System Design and Construction of earthwork and excavation, is a very complex system engineering, not only related to interactions excavation and soil structure, but also to strength, deformation and stability.An envelope in Metro Tianjin, subject to the pit wall structure to even form the main structure of the subsidiary SMW method pile form, the article on the construction technology and quality control in Metro Tianjin envelopes SMW Method piles were analysis.
