摘要

在"5.12"汶川地震中,四川省德阳市遭受了罕见的灾害损失,全市100余座水库大坝出现了不同程度的险情。通过现场核查,在对相关资料统计分析的基础上,分析了地震对水库大坝的震害特征和影响大坝安全的主要因素,震险水库的破坏形式以剪切破坏为主。破坏程度与水库大坝到震中的直线距离有关,另外,坝高、库容、坝体断面尺寸、坝型等也是影响破坏程度的因素。提出了相应的处理措施和建议。
In "5·12" Wenchuan earthquake,Deyang City suffered seldom disaster loss,more than 100 reservoirs emerged different dangers.Through in-site check and on the base of data statistics,the damage characteristics of the reservoirs by earthquake and the main influence factors on the dam safety are analyzed.The main destructive form of earthquake damaged reservoir is shear failure.The destructive degree has relation to the straight distance from reservoir to epicentre.In addition,dam height,reservoir capacity,cross-section of dam and dam type etc.are all influence factors to the destructive degree of dam.In light of the influence factors,the correspondent treatment measures and suggestions are put forward.
