φ1000mmSMW工法在大型深基坑工程中的应用

Application of SMW Method (φ1000mm) in Large Type Deep Foundation Pit Projects

通过某大型深基坑工程应用φ1000mmSMW工法对原地下连续墙围护结构进行优化设计的实践,介绍了大直径SMW工法理论受力分析、施工工艺及施工质量控制的关键措施等。对围护结构优化前后的比较分析,在经济性和技术性上SMW工法在深基坑围护工程中应用有十分明显的优势。

Through a case of SMW method(φ1 000 mm) applied in the optimization design of existing underground continuous wall-enclosure structure, the large diameter SMW method is introduced in this paper. Its key measures are put forward such as theory stress analysis, construction technique and quality controlling,etc. SMW method has obvious advantages about deep foundation pit enclosure projects in economy and technology through a comparative analysis before and after enclosure structure optimization.
