SMW 工法桩在城市泵闸深基坑工程中的应用

Application of SMW Construction Pile in Deep Foundation Pit Engineering of Urban Pump Gate

摘要:

以上海市中横沥南泵闸基坑工程为背景，对比论述了SMW工法桩在河道泵闸基坑工程中的优势。主基坑范围内的支护结构沉降、位移监测数据均满足基坑的安全要求，水泥土抗渗性能优越，分析表明，该支护形式在上海地区淤泥质土层中有良好的适用性。

Abstract:

Taking Shanghai Zhongheng Linan Pump Gate Foundation Pit Project as the background, the advantages of SMW construction pile in the foundation pit engineering of river pump gate are compared and discussed. The supporting structural settlement and displacement monitoring data in the range of the main foundation pit are all meet the safety requirements of foundation pit. The anti-penetrability performances of cement soil are excellent. The analysis shows that the supporting type has the good applicability in the silty soil layer of Shanghai area.
