| 摘 要： | 从与山地灾害关系密切的地质环境条件入手,选择了岩性和断裂带大指标,以龙门山区为典型区,根据灾害发生学原理,建立敏感性评价模型,定量分析了岩性、断裂带等对山地灾害的敏感性,并根据敏感性指标对研究区进行了敏感性区分。结果表明:岩性对山地灾害的敏感性从大到小依次为次硬岩硬岩软岩层极软岩层;断裂带对山地灾害的敏感度主要集中在距离断裂带0~2 km范围内。

| Abstract: | With Longmen Mountain area as the typical one,according to the principle of disaster science,a sensitivity assessment model is constructed by selecting lithology and fracture zone as the indexes,which are closely related with geological disasters.Then the sensitivity of lithology and fracture zone to mountain disasters is quantitatively analyzed with this model,and the Longmen Mountain area is divided according to the sensitivity indexes.The result shows that the sensitivity of lithology to mountain disaste... |
