摘　　要：提出了对同类桩—土体系利用低应变测试技术与静载荷试验的结果进行相关分析、建立回归模型 ,在此基础上对其它同类桩—土体系的基桩利用低应变测试方法测定单桩承载力 ,该方法已得到了令人满意的实际效果。The paper put forward a new method of measuring the bearing capacity of a pile foundation. The correlative analysis to the same pile-earth system and the regression model were established with low-strain measuring technology and the result of the silent load test. On these of basis, the bearing capacity of pile foundation in the area can be measured with low-strain measurement technology. This method had got a satisfactory result in practice.

关 键 词：基桩承载力 动静相关分析 回归模型 低应变测试 静载荷试验
