| 中文摘要 | 采用时域显式有限元方法,将库底非饱和淤砂层近似模拟为不同于库水的流体介质。以小湾拱坝为例,分析可压缩库水条件下库底非饱和淤砂层对高拱坝地震反应的影响。计算结果表明非饱和淤砂层的存在有可能使得坝体地震响应增加。; With the Xiaowan Arch Dam taken as an example,the unsaturated sediment layer at the bottom of the reservoir was simulated as the fluid medium,which was different from the reservoir water,and the time-domain explicit finite element method was used for analysis of the effect of the unsaturated sediment layer on seismic responses of the dam under the condition of compressible reservoir water.The result shows that the unsaturated sediment layer may lead to the increase of dynamic seismic responses of the dam.; 国家自然科学基金资助项目(50309005); 北京市教委科技发展项目(KM200310005017) |
