英文

Effect of soft rock controlled entirely on structural stability of preparatory workings, adjoining rock
控制軟巖層對采準巷道圍巖結構穩定的作用Stability of rock slopes is generally controlled by the structure of rock masses, especially the soft structure surfaces. analysis of rock mass structures is a key to establish geological models and numerical simulation and a foundation to assess the stability of rock slopes. the weak structure surfaces are mainly bedding planes, faults, joints, schistosity plane and contact zones of intrusive bodies. since they are different in genesis and scale, the rock masses are different in features and mechanical intensities. based on the combination of rock structure bodies, 15 basic modes of deformation and failure of rock slope are systematically summarized. the deformation and failure of rock masses actually result from the recombination and rearrangement of these rock bodies. there are 11 types of rock mass structures and various deformation and failure of bank slopes are present in the reservoir area of the three gorge project
巖體結構，特別是軟弱結構面對基巖斜坡變形與破壞具有顯著的控製作用，巖體結構模式分析是建立斜坡地質模型和數學模型的關鍵和評價斜坡穩定性的基礎。巖層層面斷裂構造節理裂隙片理與劈理以及侵入體和圍巖的接觸帶等是控制基巖斜坡穩定的軟弱結構面，這些成因不同大小不一的結構面將巖體分割成性質各異力學強度不均的各種巖體結構體，構成了15種基巖斜坡變形破壞的巖體結構基本模式。不同結構體的重新組合與排列是斜坡失穩的內在原因。Study on computation method for casing load induced by soft rocks
