| 摘 要： | 根据可压缩流体运动方程，推导建立了求解挡水结构动水压力的时域有限元公式。所建议的分析方法能够考虑表面重力波的影响、水体可压缩性、水库上游辐射阻尼等各种因素作用。通过算例，主要讨论了库水表面波、水体可压缩性等因素对动水压力的影响。

| Abstract: | Based on the movement equation of compressible fluid, a time-dependent finite element formula for analysis of hydrodynamic pressure on retaining structure during earthquakes is derived. The analysis method proposed can take into consideration of the effects of water surface gravity wave, water compressibility, and radiation damping at up-stream of reservoir. Case studies are presented to illustrate the effects of surface wave of reservoir water, compressibility of water body and other factors on the hydrodynamic pressure. |
