摘要： 在桩承载力自平衡法测试技术中，可以采用桩端岩基平板载荷试验测试桩端阻力，从而推定单桩抗压极限承载力，该方法拓展了自平衡法测试技术的应用；通过14根桩的测试成果，说明采用本法测试基桩承载力是合理的。

Abstract: This paper presents case histories of applying the selfbalancing load test method to the rockbearing bored piles. The ultimate axial capacity of the rockbearing bored piles can be estimated from the plate load tests on the bedrock. A total of 14 selfbalancing load test results on the rockbearing bored piles are documented. It is concluded that the estimating of the ultimate axial capacity of the rock bearing bored piles using selfbalancing load test method is reasonable.
