摘    要:汉江蜀河水电站属Ⅱ等大(2)型水电站,水库的运行对库岸的稳定性可能造成一定的影响,甚至诱发库岸失稳灾害,这势必会影响岸坡上铁路的正常运营,所以水库运行对岸坡和铁路路基的稳定性影响必须进行分析评价。历年来分析斜坡稳定性的方法很多,可单一的某一种方法并不能准确的评价斜坡的稳定性。本文以地质背景为基础,结合具体坡段的岩性、结构特征等划出典型段落,然后分别运用了坍岸预测、模糊评判、稳定性力学分析和数值模拟分析等多种方法综合对棕溪段铁路路基稳定性进行了分析评价。

关 键 词:路基稳定性  水库运行  水电站  汉江  数值模拟分析  分析评价  稳定性影响  斜坡稳定性  库岸失稳  铁路路基  地质背景  结构特征  模糊评判  力学分析  岸坡  坍岸

Abstract:Shuhe hydraulic power plant is a large scale power plant, whose operation may impose an influence on reservoir bank stability and railway roadbed stability on both slopes of the reservoir. So we must analyse and assess reservoir bank and railway roadbed stability. Available methods on slope stability analysis are in large number, but no a method which is superior to others in any cases. Based on the local geologic settings and combined the lithology and structure features, comprehensive analysis was carried out using prediction for reservoir bank caving, fuzziness analysis, stability mechanical analysis, and numerical simulation.
