采用有限元软件对跨海桥梁管桩涡激振动进行了数值模拟，分析了流速，土体刚度对管桩振动幅值的影响，结果表明：流速越大，桩体振动幅值越大，振动越剧烈，在相同流速下，土刚度对管桩振动幅值有着明显抑制作用，是一项不可忽略的参数。

A numerical simulation of vortex-induced vibration of a cross-sea bridge pile by means of the finite element software,it studies the flow velocity,the soil stiffness influence on the amplitude of pile vibration. It can be concluded that the greater the fluid velocity,the bigger vibration amplitude of the pile and the more severe vibration,the soil stiffness has obvious inhibitory effects on the amplitude of pile,is a parameter which can not be ignored.
