HEC-RAS软件在梯级水库溃坝分析中的应用OA

There are numerous cascade reservoirs in Lianzhou,Qingyuan City,Guangdong Province.When the flood control standard of an upstream reservoir is lower than that of a downstream reservoir,it is necessary to consider the impact of the upstream reservoir's failure on the downstream reservoir according to relevant calculation specifications.This paper takes Panjiadong Reservoir and its downstream Tanling Reservoir as examples,using HEC-RAS software to model and quantitatively analyze the impact of the dam break of Panjiadong Reservoir on Tanling Reservoir.The results are compared and validated with the empirical formula method to assess the rationality of the modeling.The results show that HEC-RAS software has good applicability and strong scalability in cascade reservoir dam break analysis.
