基桩自平衡法静载试验的工程实例研究

An Engineering Case Study of Static Load Test of Foundation Pile by Self-balancing Method

文中以实际工程为例,通过制定自平衡法静载试验方案及搭建自平衡静载试验装置,对自平衡静载试验承载特性展开研究,得到自平衡静载试验现场检测结果,然后绘制出相应的Q-s曲线、等效Q-s曲线和lgt-s曲线。根据自平衡静载试验现场检测到的数据得出结论,该工程桩上、下段桩在最大荷载作用下均未达到极限荷载状态。

Taking the actual engineering project as an example,the bearing characteristics of the self-balancing static load test were studied through the formulation of the static load test scheme of the self-balancing method and the construction of the static load test device,the field test results of the self-balancing static load test were obtained,and the corresponding Q-s curve,equivalent Q-s curve and lgQ-s curve were drawn.According to the data of self-balancing static load test,it is concluded that the piles in the upper and lower sections of the project have not reached the ultimate load state under the maximum load.
