Criterion and patterns of debris flow blocking big river based on water and sediment dynamic processes
摘要
Abstract
According to the characters of the submerged disk and the density current,the runout equations of the debris flow in the water is obtained, and the equation of the head-water level is given by the broad-crested weir theory. Based on the dynamic equation of the debris flow at different slopes,water and sediment dynamic processes, and the interaction between barriers dam of debris flow and main river were considered,and a model of the runout distance of debris flow in big river was established. In view of the phenomenon that the material erosion is very serious when debris flowing into big river,the erosion coeffi⁃cient is obtaineding using the test dates of flume experiment. Based on the total amount equation of debris flow was blocking given by Bifan ZHOU, a modal of the total amount of the big river blocked by debris flow was considered in hight of the erosion coefficient. The criterion of debris flow blocking big river was presented in terms of dynamic process and total amount of debris flow.关键词
