摘要: 采用实测典型水沙过程,对溪洛渡、向家坝、三峡梯级水库基于沙峰调度和基于汛期“蓄清排浑”动态使用的联合排沙调度方式开展了计算研究。结果表明:基于沙峰调度的梯级水库联合排沙调度方式从定性分析来看有利于提高梯级水库出库沙量,但提高的幅度有限;基于汛期“蓄清排浑”动态使用的梯级水库联合排沙调度方式有利于提高梯级水库出库沙量,且提高的幅度相对较大。通过计算研究提出了基于沙峰调度和基于汛期“蓄清排浑”动态使用的溪洛渡、向家坝、三峡梯级水库联合排沙调度方案,研究成果可为溪洛渡、向家坝、三峡梯级水库汛期泥沙调度提供科技支撑。

Abstract: According to typical water and sediment processes, we calculated the joint desilting scheduling of Xiluodu, Xiangjiaba and Three Gorges cascade reservoirs in two modes, respectively: sediment peak regulation mode, and dynamic mode of “storing clear water and releasing muddy water” in flood season. Results revealed that the scheduling of cascade reservoirs in sediment peak regulation mode could improve, to a limited extent, the outbound sediment discharge of cascade reservoirs in qualitative sense; the dynamic mode of “storing clear water and releasing muddy water” in flood season is conducive to improving the outbound sediment discharge to a large extent. Furthermore, we proposed corresponding joint desilting schemes in sediment peak regulation mode and dynamic mode of “storing clear water and releasing muddy water” in flood season for Xiluodu, Xiangjiaba and Three Gorges cascade reservoirs.

Key words: joint desilting, sediment peak regulation, storing clear water and releasing muddy water, Three Gorges Reservoir, Xiluodu reservoir, Xiangjiaba reservoir
