结合实例,对常用基坑支护及止水方法进行了比选,介绍了在饱水砂层深基坑中采用的悬臂式双排桩支护及高压旋喷止水帷幕技术.通过理论计算和监测数据分析了双排桩的支护效果,并探讨了高压喷射注浆止水技术在基坑支护中的应用.

Cantilever Type Double-row Piles Retaining and Groundwater Treatment for Deep Foundation Pit in Saturated Sand

With field cases, the comparison and selection were made on commonly used foundation pit support and water-stop methods; the introduction was made on the double-row piles retaining and high-pressure rotary jet grouting water-stop curtain in saturated sand deep foundation pit. Based on the theoretical calculation and monitoring data, the supporting effect was analyzed, and the application of high-pressure jet grouting water-stop technique was discussed.
