    三峽水庫蓄水后，滑體內的地下水位將明顯抬高，庫水以下的滑帶力學參數會進一步降低，受滑體內地下水揚壓力及水庫水位降落時滲透壓力的影響，四道溝滑坡在控制工況下可能整體失穩。
  3. ( 5 ) conclusion was obtained by the analyzing and studying the mechanics environment of the rock mass and the landslide on right bank : according to the analysis, the present direction of the maximal principle stress was consistent with the present tectonic stress field, the value of the principle stress increased or reduced in special place, and there was tensile stress region at the 2000m or above it on the left bank, the accumulate and adjustment was very limited in 200 years, the calculated result of the landslide indicated that the landslide on the right bank was stable under the various conditions

    （ 5 ）壩址區河谷巖體力學環境及右岸古滑坡體的穩定問題分析得出：河谷巖體應力場的分析顯示，河谷巖體中主應力的方向基本上與現今區域構造應力場的方向一致，在一些特殊地帶巖體的主應力值有所降低或增高，特別是在左岸的2000m高程附近及以上，存在有明顯張應力區。在未來200年流變計算時步范圍內，河谷巖體應力的積累與調整較為有限。同時對滑坡體各種工況條件下的穩定性計算結果表明，右岸古滑坡體在各種工況條件下是處于穩定狀態的。
  4. ( 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。
