reservoir bank stability
解釋
庫岸穩定性-
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。 -

( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced, the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ), but when the water lever suddenly fell and did not think of other force, safe factor evidently reduced, the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter, the landslide will be destroyed too
（ 6 ）建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出：建壩后河谷的巖體應力量值明顯增高，同時左岸的張應力區的范圍及量值明顯減小，主應力的方向依然與模型的底邊界垂直；大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時，滑坡體及壩體總體上仍處于穩定狀態；水位驟降時，在未考慮其他外力作用的情況時，滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用，壩體將在滑坡體下滑推力的作用下產生破壞；建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出，在最危險的工況條件下，壩體及滑坡體也將處于臨界狀態；在長期滲透變形的作用下，由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。 -
