| 摘 要： | 本文用加权余量法求解具有部分吸收库底边界时刚性坝的动水压力.在分析中,假设库水为无粘性可压缩液体,坝一水系统简化为二维问题,上游坝面的几何形状可以是任意的.数值算例表明,本文建议的方案对于分析复杂边界条件下的水动力学问题是十分精确和有效的.

| Abstract: | In this paper, the hydrodynamic pressure of rigid dam with partially absorptive reservoir bottom boundary is solved by weighted residual-point collocation method. In this analysis, the water is assumed to be compressible but non-viscous liquid and the dam-water system to be a two-dimentional problem, the upstream surface of the dam to be vertical or of any shape.The results from the numerical analysis employed show that the recommened method is a very effective and accurate one for analyzing hydrodynamic problems with complex boundary conditions. |
