钻孔灌注桩抗压承载力试验方法的对比分析

Comparative analysis on compressive bearing capacity test methods of the drilled grouting pile

针对苏州轨道交通2号线太平车辆段上盖物业开发项目钻孔灌注桩工程,采用堆载法和自平衡法进行抗压承载力静载试验。概述了本次试验情况,整理了试验数据,并将堆载法与自平衡法试验数据进行了对比分析,得出了本工程中自平衡法修正系数K的取值。分析结果表明:两种试验方法均取得了较好的效果,自平衡法表现出一定的优越性。

The drilled grouting pile engineering of Taipingcheliang project on Suzhou metro line two has been tested using the traditional piling-up weights method and the self-balanced method to carried out the compressive bearing capacity test. Tests were overviewed as well as the data to compare two different methods. Correction factor K of self-balanced method in this project was achieved. Results indicate that both of two test methods are effective while self-balanced method is better.
