| 摘 要： | 通过对横山岭水库溢洪道下泄洪水进行三维数值模拟,得出了设计洪水会淹没、冲刷坝脚,给大坝造成安全隐患的结论.并利用数值模拟技术验证了对溢洪道下游阻水山体采取开挖的疏导措施可以避免洪水威胁大坝的安全.通过这次泄洪流场模拟,开拓了三维数值模拟技术在大坝安全鉴定和除险加固中的应用.

| Abstract: | Through the 3D numerical simulation of spillway flood of Hengshangling reservoir,the paper draws a conclusion that the dam has a safety hidden trouble because of the saturation and erosion of the design flood.Then by making use of the numerical simulation technology,the dredging measure that excavates the ridge which blocks water on the downstream of the spillway can avoid the safety threat of flood.For the simulation of the flood-field,the 3D numerical simulation technique is further developed in the appli... |
