岩质边坡稳定性影响参数敏感性分析

摘要

将抗剪强度折减系数法原理与FLAC软件相结合，从工程地质、稳定性分析与评价三方面，求解边坡稳定系数，系统地研究了岩质工程高边坡的稳定性问题，利用边坡稳定系数作为边坡失稳判断依据，通过计算确定稳定性系数K与岩体力学参数的关系，找出敏感性最强的因素，可以为边坡防治设计提供合理的方案。%Combining with the principle of the sheafing strength reduction coefficient method and FLAC software, the paper solves slope stability coefficient from the engineering geology, the stability analysis and the evaluation, researches the stability of the high slope of the geotechnieal en- gineering systematically, adopts the slope stability coefficient as the reference for the judgment for the loss of stability, identifies the relationship between the stability coefficient K, and the geotechnical dynamic parameter according to the calculation, and finds the most sensitive factor, so as to provide some reasonable scheme for the slope prevention design.
