摘　　要：针对某软土基坑采用预应力复合土钉支护,对基坑变形、土钉受力等进行现场测试与分析,比较全面地得到了在软土基坑中采用预应力复合土钉支护时基坑变形与土钉受力的变化规律,其规律与一般土钉支护不同。Against a soft Soil foundation pit using prestressed composite soil nail, the pit deformation, soil nail stress, and other site testing have been analyzed. Having get the deformation and the changes of stress rule in the soft soil foundation pit which was supported by prestressed composite soil nail and finding the rules are different form general soil nail support.
