| Abstract: | This paper discusses the sluicing problems of Tangjiashan quake lake by using the data chosen from complex reports.Based on flow mechanics theories,we build up a composite mathematical model on the flow capacity and expending problems,simulate the breaching and routing process of the floodwater,and compute the depth and arriving time of downstream flood peak if one third of the water in dam pours.According to these,a decision of how to organize people to depart can be made. |
