摘　　要：甘肃民乐—山丹MS6.1级地震虽属中等强度地震,但却造成了大量房屋的破坏,且夺去了10人的宝贵生命,这充分暴露出了我国西部贫穷地区一些建筑结构抗震能力极差的弱点。列举了地震区内不同结构类型房屋及民乐、山丹两县水利系统各种结构在这次地震中的表现。通过对其震害的描述,初步分析了破坏原因,并相应提出了一些建议。Although the intensity of M6.1 Minle-Shandan,Gansu,earthquake was moderate,but in the earthquake a lot of houses damaged and 10 people died, which fully exposed the absence of structural anti-seismic capacity in wast poor area of China.
