摘　　要：为使泄槽在水库加固工程中发挥出更高的效能,降低陡坡断面水深差值、保证溢洪道泄槽体内水流变化稳定,文章以某水利加固工程项目为例,开展溢洪道泄槽体的优化设计研究。使用不对称斜切导向窄缝鼻坎的消能工布置,设计水库加固工程中溢洪道泄槽泄洪防护;通过对弯曲溢洪道泄槽的水力学模型实验,得出弯曲和扩散段对泄流的影响,以此为依据,优化溢洪道泄槽体型;计算边墙中的挡墙结构抗倾覆稳定水平、边墙抗滑稳定系数,将计算结果作为依据,进行泄槽体边墙结构的抗滑设计。设计的优化方案在投入使用后,经检验证明:设计优化方法的应用效果良好,该方法可以在减少陡坡断面水深差值、保证溢洪道泄槽体内水流变化稳定的情况下,提高泄槽体边墙抗滑稳定系数。In order to make the chute play a better role in the reservoir reinforcement engineering,reduce the water depth difference of the steep slope section,and ensure the stability of the water flow in the spillway chute,taking a water conservancy reinforcement engineering project as an example,the optimization design of the spillway chute is carried out.The energy dissipation layout of using asymmetric inclined cut to guide water to narrow-slit bucket is carried out to design the flood discharge protection of spillway chute in reservoir reinforcement engineering.Through the hydraulic model experiment of the curved spillway chute,the influence of the curved and diffusing section on the discharge is obtained.Based on this,the shape of the spillway chute is optimized.The anti-overturning stability level of the retaining wall structure in the side wall and the anti-sliding stability coefficient of the side wall are calculated.Based on the calculation results,the anti-sliding design of the side wall structure of the chute is carried out.After the design optimization scheme is put into use,it is proved by test that the application effect of the design optimization method is good,which can improve the anti-sliding stability coefficient of the side wall of the chute under the condition of reducing the water depth difference of the steep slope section and ensuring the stability of the water flow change in the spillway chute.
