| 摘 要： | 针对波浪荷载作用下砂质海床瞬时孔压响应问题,结合波流水槽模型试验实测结果,运用FLAC程序建立相应的流-固耦合本构模型,通过FISH函数使数值模型中的波浪加载与线性波理论相一致.并将数值模拟结果绘制成图和实测值进行比较分析,这是对FLAC渗流模块运用的拓展,以此进一步说明 FLAC有较好的模拟波浪加载下海床孔压特性的能力.

| Abstract: | For the problem of wave-loading transient pore pressures response within the sandy seabed,this article is based on the results of wave flume model tests and uses FLAC program to build fluid-solidity coupled mechanical constitutive model which combines permeation fluid mechanics with linear wave theory to propose a new numerical simulation method of wave-induced transient pore pressures in the sandy seabed.The results obtained by numerical simulation and the measured values will be drawn together on one grap... |
