原文提供的方法对于直线垻坡的一维问题的计算是有效的,但很难应用于实际河谷的空间问题,也不能应用于上游面具有折线垻坡的一维问題。本文将指出如何利用电拟法与格柵法相结合以计算满库时坝体自由振动的空间问題。假定库水是不可压缩的。振动时,动水压力满足调和方程。边界上各点的动水压力p决定于该点 The method provided by the original text is effective for the calculation of one-dimensional straight slopes, but it is difficult to apply to the spatial problems of actual valleys or to the one-dimensional problems that the upstream faces have polyline slopes. This article will point out how to combine the electric method with the grid method to calculate the space problem of the free vibration of the dam body in the full reservoir. It is assumed that the reservoir water is incompressible. Vibration, hydrodynamic pressure to meet the harmonic equation. The hydrodynamic pressure p at each point on the boundary is determined at this point
