| 摘 要： | 三峡库区及邻近地区滑坡地质灾害受地质构造、地貌单元、地层岩性、大气降水等因素的制约,构造-岩性-地貌组合条件控制着滑坡地质灾害的形成与分布;强烈的新构造运动控制了滑坡体的集中分布地段,大型滑坡主要密集分布在地貌阶梯附近;构造应力场与滑坡滑动方向有密切关系;地貌深切的河谷及丰富的降水利于滑坡发育;滑坡发育过程实质上也是一种地貌发育形成变化的过程。在此基础上,以杨家屋场滑坡为例,对三峡库区及邻近地区滑坡发育宏观地学背景进行了分析,以便对该地区滑坡发育有新的认识和更深的研究。

| Abstract: | Landslide disasters at Three Gorges Reservoir area and nearby are constrained by the geological structure,geomorphologic units,lithology,precipitation and other factors.The construction-lithology-geomorphologic combination of conditions is in control of the formation and distribution of landslide geological disasters.Strong new tectonic movement controls the convergence of landslide distribution.The large-landslides mainly distribute near the geomorphologic ladder;tectonic stress field is closely related to... |
