摘　　要：静载荷试验以其数据的直观准确,深得建筑工程人员的信赖。但这种方法一般往往只能从p-s曲线及s-lgt曲线分析基桩的受力特性判定其存在的问题,对于问题的成因、缺陷的类型,难以定论。为解决这一问题,将静载荷试验与低应变测试结合起来,既可以准确确定承载力大小,又可以较准确判定桩身质量情况。The data of static load experiment was visual and accurate, so the architecture workers trusted them. But this method determined the problems only with the curve p-s and s-lgt analyzing the character of foundation piles. The shortcomings of this method were that it was uncertain to decide the cause of the problems and the style of the flaws. To solve the problems, the static load experiment was combined with low strain test so that the carrying capacity and the quality of pile body were all decided accurately.
