摘　　要：自平衡法桩承载力测试方法,是一种可直接测得桩端阻力与桩侧摩阻力的静荷载试验新方法,该方法位移测量准确,较于传统的静载试验方法更为经济、快速、安全,能够满足大吨位桩基静载试验检测的要求,且不受场地限制,是未来静载试验发展与进步的新方向。通过介绍自平衡法的试验原理、试验方法,并结合工程实例,叙述了利用此法进行桩基承载力试验及结果分析的基本过程,可对相关行业在新方法的应用研究层面提供一定的参考借鉴。Self-balance pile testing methods,a new method of directly measuring the load test of static pile tip resistance and side friction of pile,the method of the displacement measurement accuracy,compared with the traditional static load test method is moreeconomic,fast,safety,which can meet the test of large-tonnage static load test of pile foundation requirements,and not subject to site constraints,is a new direction for the future development and progress of the static load test.Through the introduction of test principle,the test method of self-balanced method,combined with engineering example,describes the basic process of bearing capacityof pile foundation test and results by using this method,which can provide some reference for application research aspects relatedindustry in the new method.
