石泉水库淤积特性分析及泄洪排沙方案优化

Sedimentation Characteristic Analysis and Desilting Scheme Optimization of Shiquan Reservoir

石泉水电站泥沙淤积治理已刻不容缓,通过分析入库水沙特性及库区淤积现状,在实际排沙方案的基础上,结合断面推移质输沙特性,提出优化排沙调度方案。优化方案符合低水位、大流量、长时间的原则,通过对典型洪水来水过程模拟,得出优化排沙方案能取得更好的排沙效果,该方案能够对后期的排沙调度过程进行指导。

The current situation and storage of water and sediment deposition in the reservoir area are analyzed. On the basis of analyzing the actual sediment program, optimization sediment scheduling scheme is proposed. Optimized program is consistent with the principle of low water level, high speed flow, and longtime desilting. Through the typical flood runoff process calculation, the optimized scheme can achieve better desilting effect. At last,The scheme can carry on the guidance to the sediment delivery scheduling process lately.
