何家沟水库除险加固工程消能墩体型和位置优化研究

Study on shape and position optimization of energy dissipation pier in danger elimination and reinforcement project of the Hejiagou Reservoir

消力池的结构优化设计有助于提高消能效果,保证泄水建筑物的安全稳定运行,具有重要的工程意义和价值。文章以辽宁省凌源市何家沟水库除险加固工程为例,利用数值模拟的方式,探讨了消能墩墩型和位置对消能效果的影响。综合模拟计算结果,建议工程设计中在消力池的池尾设置T型消能墩。

The structural optimization design of stilling basin is helpful to improve the energy dissipation effect and ensure the safe and stable operation of discharge structures,which has important engineering significance and value.Taking the danger removal and reinforcement project of the Hejiagou Reservoir in Lingyuan,Liaoning,as an example,this paper discusses the influence of energy dissipation pier type and location on energy dissipation effect by means of numerical simulation.Based on the simulation results,it is suggested to set T-shaped energy dissipation pier at the end of the stilling basin in the engineering design.
