摘　　要：基于杭州萧山机场三期项目中关于综合管廊二区的复杂基坑围护工程,分析了高压旋喷桩在低净空、狭小场地基坑支护中所具有的优势。结果表明:利用高压旋喷桩内插H型钢的支护方式,有效地解决了地下市政管线复杂的施工障碍难题;同时,该方法能有效缓解施工场地占用和保证工程施工进度,发挥出了良好的经济和社会效益。In this paper,based on the complex foundation pit support engineering of comprehensive pipe gallery area II in Hangzhou Xiaos-han Airport Phase III project,the advantages of high-pressure jet grouting pile in foundation pit support of low clearance and narrow field are analyzed.The results show that:the support method of high-pressure jet grouting pile inserted with H-shaped steel effectively solves the difficult problem of complicated construction obstacles of underground municipal pipeline;at the same time,the method can effectively alleviate the occupation of construction site and ensure the construction progress,and has played a good economic and social benefits.
