单桩水平静载试验及成果参数取值探讨

Horizontal Static Load Test of Single-pile and Its Parameter Values Discussion

通过现场PHC管桩的水平静载试验,对单桩水平临界荷载、水平极限荷载和地基土水平抗力系数的比例系数m进行了判定,分析了m值与水平荷载和水平位移的关系,并对m的合理取值提出了初步建议.

The horizontal critical and ultimate loads of single-pile and its corresponding proportional coefficient m of the horizontal resistance coefficient in foundation soil are judged through horizontal static load test on PHC pile. Relationship between m and horizontal load or displacement was analyzed. As a result, primary suggestions on reasonable value ofm were proposed.
