摘　　要： 2008年5月12日14:28四川省西部龙门山山区发生Ms=8.0级强震。地震是由龙门山中央断裂逆冲兼走滑产生的,沿300 km长的断裂带造成大量的山体崩塌、滑坡,城镇与村庄房屋坍塌不计其数,厂矿与交通设施严重毁损,并造成大量的人员伤亡。截至7月11日12时,地震已造成69 197人遇难、18 341人失踪、374 176人受伤。基于震后灾区的第一手调查资料,在简介龙门山地质条件与断裂构造格局的基础上,从工程角度对地震产生的震害类型和分布,及其与断裂构造的关系等进行初步的总结和归纳,提出灾区重建工作中面临的主要岩土工程问题,以期为灾后重建和相关科研工作提供参考。 At 14： 28, May 12th, 2008, a large earthquake measured Ms = 8.0 hit Longmenshan mountainous area, west Sichuan Province, China. The earthquake was induced by the thrust and strike-slip of Longmenshan central fault and its 300 km-long fault rupture resulted in a large number of rock avalanches and landslides, destroyed numerous villages and towns, leading to many human fatalities. By 12： 00, July 11th, the earthquake has caused 69 197 peoples to die, 18 341 peoples to be missing, and 374 176 peoples to be injured. Based on field reconnaissance, the geological conditions and fault patterns in Longmenshan mountain area are introduced briefly; the types and distributions of disasters and their relations with fault pattems are summarized from the engineering viewpoint. And then the major geotechnical problems to be faced in post-quake reconstruction are put forward, so as to provide references to reconstruction and further researches.
