【Abstract】 The minimum depth of the spillway tunnel from the slope s urface on the right side is only 10m whi le on the spillway left side the mountia n has a height of 100m.Therefore,the in situ stress on the right side of the spi llway tunnel is much higher than that on the left side.In this paper stability o f the slope and unbalanced side pressure of the spillway tunnel during its excav ation are studied by using nonlinear fin ite element method.更多还原
