Abstract The slope behind the powerhouse and the intake tunnel outlet of Geheyan power station is very high and large with rigid rock on the top and soft rock on the underside. There are several groups of cracks and faults，and there is a instable rock mass in the eastern and western areas，respectively. Several bends are considered for the reinforced project during construction. The deformations on the surface and in the deep are very small，which indicates the slope during the operating period is stable.
