瀑布沟水库防洪调度方式研究

瀑布沟水库的防洪库容、汛限水位以及防洪任务较设计阶段发生了较大的变化,为充分发挥瀑布沟水库的综合效益,有必要对水库的防洪调度方式进行优化。本文以分析防洪任务、复核防洪现状、划分防洪库容、拟定防洪调度方式为研究思路,分析计算下游安全泄量;采用区间峰值补偿的方法计算分配防洪库容;根据各段防洪库容的任务优化拟定相应的防洪调度方式。分析结果表明,优化后的防洪调度方式在保障水库完成防洪任务的前提下,能更好地发挥其综合效益。

Study on flood control operation mode of Pubugou Reservoir on Daduhe River

As the flood control capacity，flood control level and flood control task of Pubigou Reservoir are largely revised in comparison with those determined during the design stage，it is neccessry to optimize the flood control mode of the reservoir for giving full play to the comprehensive benefit of it.By taken analyzing the flood control task，re-checking the status of the flood control，dividing the flood control capacity and determining the flood control operation mode as the study objects，the downstream safety discharge is analyzed and the flood control capacity is allocated with the method of compensating the interval peak value，and then the corresponding flood control operation modes are made in accordance with the optimizations of the flood control capacity tasks at all the phases concerned as well.The analysis result shows that the optimized flood control operation mode can better make the reservoir play its comprehensive benefit under the premise of ensuring the fulfillment of the relevant flood control task.
