【摘要】 2008年5月12日14时28分汶川发生的8.0级大地震对我国四川省西部及西北部县市造成了特别严重,甚至是毁灭性破坏.基于现场调查资料,分析了彭州灾区的灾害空间分布,描述了典型建筑物破坏和大型滑坡体等地质灾害现象,并结合彭州地区房屋抗震设防情况,对此次地震灾害的主要成因进行了分析.结果表明,本次地震灾害的主要成因包括震级大、破坏力强,滑坡崩塌等地震地质灾害严重,农村建筑物缺乏必要的抗震设防措施等.在未来的规划与建设中,应避开断层、滑坡危险区域,并加强对农村地区建筑物的抗震设防指导.更多还原

【Abstract】 A devastated MS8.0 earthquake struke Wenchuan county, Sichuan province on May 12, 2008, and razed many counties in western Sichuan pronvince.
