Research on the Dam Foundation Stability and Reinforcement Measures of the 12th Sluice Section of Xiangjiaba Hydropower Station

Abstract:

By two-dimensional nonlinear finite element strength reserve coefficient method and the rigid body limit equilibrium method respectively, a comprehensive study of the stability of the 12th sluice section of XiangJiaba hydropower station is made and some conclusions of the instability mode and the lack of safety are reached. The reinforcement measures, which set up concrete cogging at the dam heel and put up additional drainage holes at the stilling basin,are proposed and calculated by the strength reserve coefficient method and the rigid body limit equilibrium method respectively again,Results show that the dam foundation safety meets the code’s standards if the . reinforcement measures are adopted.
