摘　　要：采用高应变实测曲线拟合法确定基桩承载力及桩侧摩阻力的分布,通过基桩承载力动、静试验结果的对比,分析了高应变实测曲线拟合法的测试精度和可靠性,探究了高应变动测法确定基桩承载力的误差来源及因由,为合理确定桩基工程设计参数提供可靠保证。This essay will determine, the bearing capacity of the pile and shaft resistance by the curve match method of high strain dynamic testing. By the pile of bearing capacity of the con trast between the testing results of static loading and dynamic high strain, analyses the reliabil- ity and surveying precision of the curve match method and exdores the error sources and rea- son, which reasonably determine the pile foundation engineering of design parameters.
