| 摘 要： | 5.12汶川特大地震给四川省水库造成了严重的震害和巨大的经济损失。依据绵阳市水库地震灾害的现场科学考察资料,对绵阳市游仙区44座高危险情以上的水库土坝的震损现象做了初步总结和分析。发现这些震损水库基本上都建于1950~1980年,未经抗震设计,典型震害现象包括水库坝顶中部及坝轴线两侧纵向裂缝、坝体纵横向裂缝和坝坡局部滑裂等,并有水库泄水构筑物震损、防浪墙倒塌、上游坡护坡下滑、坝坡挡土墙倒塌等。这说明对小型水库土坝进行抗震设防是必要的,今后应深入研究小型水库土坝的震害机制,以指导水库土坝的抗震设计。

| Abstract: | The great Wenchuan earthquake on May 12,2008 destroyed severely the earth dams in Sichuan Province and induced enormous economic losses.The damages of 44 earth dams of the high grade of risks in Youxian District,Mianyang City, Sichuan Province were analyzed and preliminarily summarized on the basis of scientific documents from the field investigation of seismic damages of reservoirs in Mianyang City,which have revealed that those earth dams destroyed in the earthquake were almost all built in the years of 1... |
