The frequent extreme weather events caused by the global warming presents a great challenge to the eco-logical environment and human survival.Especially,the dam-break problem has been a research focus in hydrody-namic field recently.The dam-break flow can result in a serious destruction of downstream structures.It is impera-tive to explore the hydrodynamic characteristics of dam-break and the interaction between the dam-break flow and downstream structures.This paper uses the CEL method(Coupled Eulerian-Lagrangian analysis)to numerically simulate the flow process and interaction of dam-break flow with structures.The results show that the CEL method has good usability and accuracy at the simulation of dam-breaking problem.The material properties,height,and location of the structure all affect the flow process of the dam-break flow and the stress strain condition of the struc-ture.Without considering the damage of the structure,by increasing the elastic modulus and height of the struc-ture,or by reducing the distance between the structure and the dam-break flow,the function of blocking the flow of dam-breaking can be improved.
