摘要
运用ALE(Arbitrary Langrangian-Eulerian)描述流体域,流体域中的网格点按照自由液面的运动和结构与液体接触面的移动而不断更新,从而将运动边界的非线性效应融入到计算中,考虑坝水完全耦合。数值模拟了四川某坝体在地震作用下的坝体的动力特性、库水自由表面重力波影响的问题以及库水域有效影响范围的问题,得出了有益的结论。
The ALE （Arbitrary Langrangian-Eulerian） description of fluid domain, fluid domain grid points of the campaign in accordance with the free surface and the structure and movement of liquid contact and constantly updated, so that movement of the non- linear effect of the border into the to dam water in the fully coupled considered under the influence of vibration. Numerical simulation of a dam dynamic characteristic in an earthquake, free surface gravity waves, the impact of effective waters area, to draw useful conclusions.
