Stability Analysis of a Spillway Slope of the Tankou Second Reservoir
Stability analysis of the slope is important for the safety of all construction projects.The stability and the excavation deformation characteristics of a spillway slope of the Tankou Second Reservoir is evaluated by the limit equilibrium method and the FLAC3D numerical method,respectively.The factor of safety of the slope,the displacement patterns,and the stress-stain relationships are studied.The results indicate that the overall stability of the spillway slope is satisfactory,with minor local failures occurred at the upper and middle surface of the excavated area.The reinforcement measures of the ground anchors with shotcrete should be adopted,as commonly used in the area.In this paper,the results of the spillway slope numerical simula-tions have provided a scientific reference for the excavation design and the reinforcement measure of the slope,which has an useful theoretical and practical significance.
