摘要
5.12汶川特大地震对绵阳市梓潼县170座水库造成了不同程度的破坏和严重的经济损失。依据绵阳市梓潼县水库地震灾害的现场科学考察资料,对绵阳市梓潼县48座高危以上险情水库土坝的震损情况做了初步总结和分析。典型震害现象包括裂缝、渗漏以及泄水建筑物和附属设施的损毁等;以梓潼县3座典型震损水库土坝为例,总结了震损水库的特点和经验教训,给出了一些建设性结论。
Wenchuan earthquake of magnitude 8.0 (Ms 8.0) occurred in Sichuan Province, China, on 12 May, 2008, inflicted damage to 170 reservoir dams in Zitong County, Mianyang City and great economic losses. The field technical investigation of the reservoir dam damage caused by this earthquake was carried out after the earthquake. The damage characteristics of 48 reservoir dams located in Zitong County were analyzed. Some typical damage, including longitudinal and transverse cracks in the dam embankments, leakages of dam embankments and some accessorial facility failure, were found in these reservoir dams. Three typical damage cases were discussed and some conclusions were put forward.
