| 摘 要： | 本文基于有限水深带形域势流问题的基本解和二维线弹性力学问题的Kelvin解,建立了坝库系统在谐激励下稳态响应的双边界积分方程.推导过程中,利用了Nardini和Brebbia方法将分布惯性力项的体积分化为相应的边界积分.然后通过边界元离散技术,针对两个不同型式的坝体计算了作用在界面上的水动压力分布,其中一个算例的结果和已有的有限元解作了比较.

| Abstract: | This paper deals with the steady-state response of a long concret gravity damreservoir system with arbitrary upstream face under a harmonic rigid base motion in the horizontal direction by employing the double BEM. Based on the Green's function for potential flow problems in an infinite strip region and the Kelvin solution in 2-D elastostatic problem, a pair of boundary integral equations for the dam-reservoir system are formulated. From the result, only a discretization analysis on the boundary of the dam is required to solve this coupled liquid-structure interaction problem. In addition, the BEM solutions are described in detail and the efficiency of the proposed method is demonstrated through two numercal example. |
