( 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。The change regularities of lining pressure and the failure process of surrounding rocks in permeation which a special sand is used as model materials are successfully simulated. the basic theory is established for the study of same type and the scientific basis for the tunnel prop design in saturation rock is provided
