| 摘 要： | 为了研究强震区高桩码头结构在地震动作用下结构的安全性,采用快速拉格朗日时域有限差分法进行地震时程分析,并利用FLAC3D软件进行某高桩码头数值模拟。结果表明:双向地震动作用下,码头结构产生的水平、竖直残余位移较小;平台纵梁正应力及横梁正应力幅值波动较大,但均在材料的允许强度范围之内;桩体轴力幅值变化较大,但均小于其承载力。从码头结构刚度、强度角度分析,码头结构安全可靠。

| Abstract: | In order to research the safety reliability of high-pile wharf in highly seismic region,fast Lagrangian analysis of continua was used for seismic time history analysis and the FLAC3D software was adopted for numerical calculation.The result indicates that the high-pile wharf generates small residual horizontal and vertical displacement;the normal stress amplitude of platform's longitudinal beam and transverse beam waves up and down,but the extreme values are all within the range of allowable strength;and th... |
