摘　　要：采用动力分析程序ANSYS/LS-DYNA建立完整桩有限元模型,在考虑桩身阻尼的前提下,获得不同接收点的速度时程曲线,采用Matlab编制的数据处理程序,将速度时程曲线分离出上下行波,经过分析得出采用双速度法用于桩身完整性检测的规律性结论。以某工程为应用双速度法为例,证明了此种方法的适用性。Dynamic analysis program of ANSYS/LS-DYNA is employed to establish a integrity fi nite element model.Under the premise of considering damping of pile,obtain the different receiver point of the speed-time curve,based on Matlab to compile data processing program,then uses the program compiled by matlab after extracting data to separate up and down waves.Through the analysis with Double speed method for pile body completeness get inspection conclusion.In a certain engineering as the application of Double speed method.Illustrate the applicability of this method.
