摘要
倾角顺层岸坡是在三峡库区内广泛分布,常发育大中型滑坡。在调查分析区内某变倾角滑坡特征的基础上,将其形成演化过程分为原始阶段、滑移阶段、弯曲阶段和剪出阶段。并用Geo-slope软件计算其稳定性。结果为该滑坡在145m工况与156m工况下基本稳定,在175m工况下欠稳定。
Bedding slopes of variable inclination are widely distributed in the Three Gorges Reservoir area, with large or medi- um sized landslides occurring often. The evolution process of one such landslide is divided into early phase, slip phase, bending stage and cut stage. And its stability is calculated with the use of the Geo slope software. The calculations show it is stable un- der the condition of 145m and 156m, less stable under the condition of 175 m.
