| 摘 要： | 通过实地调研5·12大地震后汶川震区附近道路沿线的滑坡与崩塌灾害分布情况,对地震烈度、地形地貌及地质构造等影响边坡动力稳定性的主要因素进行了分析.经过统计表明,沿发震断层长轴方向的地质灾害点数目明显地比垂直于断层的短轴方向比较多;地震滑坡、崩塌等地质灾害在该区域分布上以沿河流水系呈线状分布;地震引发的滑坡多集中在坡度2...

| Abstract: | Based on spot investigation for landslide and collapse distribution in seismic area of Wenchuan earthquake,the main influenceing factors of slope dynamic stability,including seismic intensity,topography,physiognomy,and geological structure,were analysed.The statistics indicates that(1) the amount of geological disasters along long axis direction of earthquake-triggering fault is obviously greater than that along short axis perpendicular to that fault;(2) the distribution features of landslide and collapse d... |
