SMW工法在基坑支护结构中的运用

SMW工法近几年在国内的基坑围护工程中发展迅速，凭借它无泥浆污染、止水性好、噪声小、工期短、施工适应性广等特点，已在上海、武汉、南京等地区的高层建筑、地铁工程、合流污水治理工程、大型工业厂房基础等工程的地下深基坑围护中得到应用。通过介绍基坑SMW工法支护结构的设计和施工控制，从结构分析、工艺流程和施工要点对SMWT法进行了较全面的阐述。

APPLICATION OF SMW METHOD IN EXCAVATION SUPPORTING STRUCTURE

In recent years, for the characteristics of no slurry pollution, good waterproof, quiet, short time period and high adaptability,SMW method is developing very quickly and had been widely used in deep excavation supporting system of some high-rise buildings, metro projects, sewage treatment works and foundation of large industrial workshops in many cities,like Shanghai,Wuhan, Nanjing, and so on. The design and construction control of SMW method used in excavation supporting structure were presented in this paper, and which was also generally described from the aspects of structure analysis.technological process and key Point of construction.
