摘要: 危岩崩塌灾害是三峡库区乃至整个西部地区主要地质灾害类型,具有泛生性、突发性、隐蔽性及致灾严重性等基本特性。危岩形成机制及破坏模式的确定是对危岩进行有效治理的前提。对危岩体稳定性三维模型公式进行推导,为危岩体稳定性计算提供了更接近实际的三维计算模型,为治理工程设计提供依据。危岩稳定性分析是复杂而困难的,利用三维模型对危岩体进行计算和治理工程设计较常规二维计算模型更合理。

Abstract: Dangerous rock collapse is the main geological disaster type in the Three Gorges Reservoir area and even in the whole western region, which has such basic characteristics as generality, suddenness, concealment and disaster severity. The conformation of formation mechanism and failure mode of perilous rock is a prerequisite to carry out the effective treatment measures on perilous rock. The formula of three-dimensional model for stability of dangerous rock mass was deduced, which provided a more practical three-dimensional model for stability calculation of dangerous rock mass and provided a basis for the design of harnessing engineering. The stability analysis of dangerous rock is complex and difficult. It is more reasonable to use three-dimensional model to calculate and control dangerous rock mass than conventional two-dimensional model.

Key words: geotechnical engineering, dangerous rock, stability, 3D model
