STABILITY ANALYSIS ON HIGH SLOPES AT OUTLET AND INLET OF THE DIVERSION AND SPILLWAY TUNNELS OF PANSHITOU RESERVOIR
盘石头水库泄洪洞、导流洞进出口高边坡稳定性分析

After systematically analyzing the engineering geological conditions of the high slopes at both the outlets and inlets of the two tunnels of the Panshitou Reservoir,Henan province,a classification of the engineering geological rock groups of the high slopes is made,then the slope failure models are proposed. The rockmass mechanics parameters of the slopes are also discussed. Based on these,stereographic projection method,limit equilibrium method and three-dimensional differential method (FLAC3D 2.00 for Windows) are used for stability evaluation of the slopes.
