摘　　要：根据高应变锤击测桩Case法和实测曲线拟合法原理,分析桩土之间阻尼模拟,建立一个与工程实际相符合的阻尼模型,给出了该模型参数的取值方法,并根据模型推导了基桩的承载力。通过五根桩的算例验证了Case法和曲线拟合法在分析基桩承载力时的显著效果。The damping simulation of pile-soil is analyzed based on the Hammering dynamic pile Case test with high strain and the curve combination method.A damping model,which is coincided with the actual project,is established,and a method for acquiring the parameters in the model is given.The bearing capacity of the pile is deduced from the model.The remarkable effect of the Case method and the curve combination method in the analysis of bearing capacity for hammering pile are verified by five examples of calculation in practical case.
