Simulation Analysis and Response Strategy of Luhun Reservoir Under Rainstorm Transplantation Scenario
The rainstorm and flood disaster caused by extreme weather events seriously threatens the safe operation of the reservoir.Starting from the concept of flood control of extreme thinking and bottom line thinking,the flood discharge capacity of the current project of Luhun Reservoir cannot meet the actual needs of excessive flood prevention in the future.By transplanting Huaihe River rainstorm occurred in Au-gust of 1975 and Zhengzhou rainstorm occurred in July of 2021 to Luhun Reservoir for flood simulation,this paper carried out the flood simu-lation analysis and coping strategy of Luhun Reservoir under the rainstorm transplantation scenario.The results show that the flood discharge capacity of the current Luhun Reservoir is insufficient,and the reservoir needs to build extra spillway;The construction quantity of Laohukou exit scheme of emergency spillway is slightly greater than that of Tanggou exit scheme,but the latter involves more difficult personnel reloca-tion,so it is inclined to the former.The extraordinary spillway design scale and scheme are proposed,and the design scale and scheme of the extraordinary spillway are optimized and improved through the model test.
