三峡库区某岩质高切坡稳定性分析

由于三峡移民建设的开展,三峡库区城镇建设形成了一系列的高切坡,给库区人民生命财产安全带来较大的危害。作者主持了库区部分高切坡防治勘察设计工作,本文通过对某岩质高切坡的地质特征、边坡类型、结构面形态、成因及与临空面的组合关系的研究,建立了该切坡变形破坏模式,通过试验和反算,取得不同工况下结构面力学参数,并对高切坡的稳定性作出了较为客观的分析和评价。

As the transfer of the people in the Three Gorges program is on the way, a number of sharp slope frequently occur in the area near the reservoir, which brings a severe threat to the local people' life and property. The author is in charge of the prospecting and designing work of preventing the formation of the sharp slope. He builds its deconstruction model through the design on its geological features, styles, shape, cause of formation, and the composite relation. According to reverse calculation and experimental statistics, this paper works out the structural side parameters and makes a external assessment and estimate of the landslide's stability.
