洪潮江水库大坝除险加固设计及稳定分析OA

For Hongchaojiang Reservoir Reinforcement Project,the hydraulic structural finite element analysis soft-ware(AutoBank)was employed to analyze the downstream seepage exit elevation,unit-width flow rate,hydraulic gradient,safety and stability coefficients of the reinforced dam under various working conditions and stable seepage.The results demonstrate that after reinforcement,the downstream seepage exit elevation and unit-width flow rate de-creased significantly,essentially resolving the leakage problem of main dam.The maximum seepage gradients in the dam fill soil and the foundation soil layers are all lower than the allowable seepage gradient,indicating that seepage failure will not occur.The anti-sliding stability safety factors of both the upstream and downstream dam slopes meet the requirements of relevant specifications.
