| 摘 要： | 汶川地震发生在青藏高原东部边界的龙门山断裂带.该区域由一系列叠瓦状冲断带构成,在大地构造上是连接青藏高原与扬子地台的过渡地带.此次地震引发了大规模的滑坡、崩塌、碎屑流等地质灾害,造成严重的人员伤亡和社会经济财产损失.震后的凋查和研究结果表明,在龙门山断裂带的两侧,滑坡崩塌灾害的分布很不均匀.大多数的滑坡崩塌存在于龙门山...

| Abstract: | On May 12,2008,a huge earthquake(MS=8.0)named Wenchuan earthquake hit Sichuan Province in Southwest China and triggered thousands of landslides.Post-seismic investigation and analysis discovered some characteristics of the landslides' spatial distribution.Landslides occurred unevenly on both sides of Longmenshan Fault zone,which are reverse faults and responsible for the Wenchuan earthquake.The majority of the landslides are distributed on the hanging wall of Longmenshan central fault,while only 12%of the t... |
