英文摘要	Amethod ofdesigning a box-type energy -dissipating section of a box -type energy -dissipating mudflow diversion flume. Firstly , the longitudinal gradient J of the flume and the roughness coefficient n 0 of a fully -lined flume bottom (1) are determined . Then , the parameters of the box -type energy -dissipating section are set, and related parameters are substituted into a formula for calculation , so that the overall roughness coefficient n of the flume is obtained . Further, the flow velocity of themudflow is calculated by means of the Manning formula . Finally , the flow velocity of the mudflow is compared with the non -scouring and non - silting velocity allowed by the flume, and the design value of the box -type energy-dissipating section is obtained through final optimization . Themethod factors in the longitudinal gradient J of the flume, the length L of the box -type energy -dissipating section , the width b of the box -type energy -dissipating section , and the average diameter D of filler stones. ith the method , the overall roughness coefficient n of the flume under different design conditions can be determined reason ably, so as to further implement the optimized design of the box -type energy -dissipating section of the box -type energy dissipating mudflow flume. Further provided is an applica tion of themethod of designing a box -type energy - dissipating section of a box -type energy -dissipating mudflow flume.
