摘　　要：为合理选定大水溪水库工程溢洪道方案,结合坝址区的地形地质条件,对左岸与右岸溢洪道布置方案、正槽式与侧槽式溢洪道形式、底流与挑流消能方式进行技术经济比较,最终按照投资节省原则选定左岸侧槽式溢洪道、挑流消能方案。通过水力计算,合理确定建筑物尺寸,并有针对性地提出基础及边坡处理措施。经近年汛期泄洪验证,溢洪道运行状态良好。文中提出的溢洪道方案比选思路及设计可为类似的工程设计提供一定的经验借鉴。In order to reasonably select the spillway scheme of Dashuixi Reservoir project combined with the topographic and geological conditions of the dam site area the technical and economic comparison of the layout scheme of the spillway on the left bank and the right bank the form of nomal channel spillway and side channel spillway the energy dissipation mode of hydraulic jump and ski-jump are carried out.Finally according to the principle of investment saving the left bank side channel spillway and the ski-jump energy dissipation scheme are selected.Through hydraulic calculation the size of the building is reasonably determined and the foundation and slope treatment measures are put forward.Through the flood discharge verification in recent years the spillway is in good condition.The comparison and selection ideas and design of spillway schemes proposed in this paper can provide some experience for similar engineering design.
