西藏地区振冲碎石桩复合地基试桩施工与检测

Construction and Inspection for Composite Foundation of Vibroflotation Crushed Stone Pile in Tibetan Area

针对采用振冲碎石桩+厚300mm褥垫层的复合地基处理方式,根据设计要求的试验检测,并结合西藏地区地质情况,对已经处理完成的复合地基进行静载试验、桩土应力比测试、动力触探等抽检检测,从而验证复合地基的施工质量。

For the composite foundation treatment method of vibroflotation crushed stone piles+300mm thick cushion layer,according to the design requirements of the test and combined with Tibetan area geological conditions,the casual inspections such as static load test,pile-soil stress ratio test,dynamic penetration,etc.for the completed composite foundation are carried out accordingly,so as to verify the construction quality of the composite foundation.
