摘要

在汶川MS8.0地震后甘肃陇东地区的详细灾害调查基础上,对该区地震破坏进行了分类研究,给出了各种建筑物及工程结构的破坏程度及破坏特征。结合该区独特的地质地理环境对产生地震破坏的原因进行了分析。认为该区地震破坏相对严重的原因除与建筑物本身质量及结构有关外,还与远震和地形影响的长周期效应及持时较长有关。
Based on the detailed disaster investigation in eastern Gansu province after Wenchuan MS8.0 earthquake,the earthquake damage in the area is classified and researched,the seismic damage intensities and destruction features for different kinds of building and engineering structure are presented.According to the unique geological conditions,the reasons for earthquake damage being more severe than expected in this area are analyzed.It is considered that the reasons for the relatively severe damage is not only relevant to the quality and structure of the building itself,but also to the long period effect caused by the teleseism,the geography influence and the long duration time of seismic wave.
