Abstract

Abstract

The controlled Lianziya hazardous rock, especially T₈-T₁₂ fracture segment will be affected over a long period of time when the Three Gorges reservoir stores water, which also relates to efficacy of the control project to the rock. Through mass field investigations and rock tests, this paper concerns with the long term effects of the reservoir to T₈-T₁₂ fracture segment and its deposits, and also recalculates the stability of the rock by using improved Sarma program. Then some new conclusions are obtained: generally, when the water level of Yangtze River rises, the water actions of erosion and tension will widen the fractures, and deteriorate the rock stability. On considering long term strengths of rock and control project, as well as rapid water rising and dropping, and also earthquake affection, the stability of hazardous rock will turn worse than before, whereas the condition in NE20° direction will be better than that in NW350°.
