摘要
Abstract
The Minghe Aqueduct is an important large water transport structure for the middle route of the South-to-North Water Transfer project.The change of external environment may bring hidden dangers to the safe operation of the project.In order to check and review the flood discharge capacity of the cross channel of the Ming River Aqueduct,based on the actual on-site measurement and digital processing,and aiming at the 100-year and 300-year design floods under different roughness conditions,a two-dimensional numerical model of flood evolution is constructed.The MIKE21 model is used to simulate the whole process of flood evolution from the upstream channel to the downstream through crossing buildings.Determine the influence of flood flow on aqueduct.The simulation results show that the most unfavorable conditions(n=0.035)meet the requirements of the flood tank body without water blocking.关键词
