四川是水电开发大省,已建和在建水利工程数量众多。汶川大地震使众多小型土坝遭受不同程度震害,四川省遭受不同程度损害的1803座水坝中,约有96%是库容不足500万方的小型工程。当务之急是防止次生灾害,其次,要深化防止高坝严重地震灾变的研究,在震害调研、复核和调整设防水准基础上,对遭受
Sichuan is a major hydropower development province, has built and under construction a large number of water conservancy projects. The Wenchuan earthquake hit so many small earth mines to varying extents, and about 96% of the 1803 dams of varying degrees damaged in Sichuan Province are small projects with a storage capacity of less than 5 million square feet. The top priority is to prevent secondary disasters. Second, we must deepen the study on preventing serious catastrophic earthquakes in high dams. Based on the survey, review and adjustment of fortification levels,
