| 摘 要： | 危岩是三峡库区重要地质灾害之一,影响危岩坡稳定性的因素有很多,但总体可归为起控制作用的内在因素和起诱发作用的外在因素两类。内因主要包括组成岸坡的地貌特征、岩土体性质、地质构造、岩土体结构等;外因包括地震、水的作用、风化、人类工程活动等。本文从岩性、岩体结构特征、水体作用、地震、人类工程活动等因素对巫峡横石溪马鞍子危岩体稳定性进行了分析研究,为今后野外高陡岩质岸坡、危岩的调查或稳定性评价提供参考。

| Abstract: | The factor effecting stability of Maanzi dangerous rock in Wu Gorge is mainly controlling intrinsic factor and inducing exterior factor.Intrinsic factor includes geomorphic feature,property of rock mass,geologic structure,and structure of rock mass,while exterior factors includes earthquake,water movement,weathering,and human engineering activity.Stability of Maanzi dangerous rock is analysis by considering lithology,rock structure,hydrology,earthquake,and human engineering activity,which maybe provide some reference to estimate the stability for high rock slop and dangerous rock in the future. |
