摘　　要：采用自平衡桩基静载试验方法对桩基承载力进行检测,详细阐述了自平衡法的试验原理、试验过程、试验结果分析。在工程应用部分,以兰州市七里河区某工程为例,详细介绍自平衡法在该项目中的应用情况,通过总结试桩的Q-s曲线变化规律,对试桩的承载力进行合理评价。结果表明,选用适当持力层的试桩均能满足设计承载力的要求。不仅验证了自平衡法在桩基承载力检测中的有效性,也为类似工程提供参考。The self-balancing pile static load test method was adopted to detect the bearing capacity of pile foundations.This paper elaborated in detail on the test principle,test procedure,and analysis of test results of the self-balancing method.In the engineering application section,considering a project located in Qilihe District of Lanzhou City as a case study,the application of the self-balancing method in this project was introduced in detail.By summarizing the variation rules of the Q-s curve of the test pile,a reasonable evaluation of the bearing capacity of the test pile was conducted.The results showed that the test piles with proper bearing layers selected could all meet the requirements of the designed bearing capacity.This not only verified the effectiveness of the self-balancing method in the detection of pile foundation bearing capacity but also provided a reference for similar projects.
