Abstract: The maximum height of the intake side slope of Xiangjiaba Hydropower Station is 150 m. Systematic Bolts will be adopted to reinforce the rock mass. Because of the passivity action of systematic bolts and the heterogeneity of rock mass deforming, systematic bolts have different stress in different position. This paper analyzes the systematic bolts’ stresses on rock mass of high side slope of the intake in Xiangjiaba Hydropower Station by using elasto-viscoplastic finite element method. We can find the obvious laws from the calculation results that the bolt stress is larger in the rockmass which has larger displacement than in one which has less displacement. And the bolt stress increases with the excavation and anchorage progresses.

Key words: Xiangjiaba Hydropower Station, high side slope at intake, FEM, systematic bolts, stress
