自平衡法与堆载法结合在特大吨位基桩竖向抗压静载试验中的应用

Application of Self-balancing Method Combined with Surcharge Method in Vertical Compressive Static Load Test of Super-large Tonnage Foundation Pile

文中介绍了某在建工程由于场地、静载吨位及地质条件等限制,传统堆载法静载试验与自平衡法均无法顺利完成检测的情况,采用了堆载法与自平衡法相结合的方式,成功完成了基桩静载试验。详细介绍了参数核算的过程以及安装与检测过程中需要注意的事项,检测结果证明了这一方法的有效性,对于解决建筑工程中类似的静载试验难题具有一定的参考价值。

This article introduces a case where the traditional static load test and self-balancing method cannot be successfully completed due to limitations in the site,static load tonnage,and geological conditions in a construction project.To solve this problem,we adopted a combination of static load test and self-balancing method,and successfully completed the pile static load test.This article details the process of parameter calculation and the precautions to be taken during installation and testing.The final test results demonstrate the effectiveness of this method,which has certain reference value for solving similar static load test problems in construction projects.
