Document Type and Number:
WIPO Patent Application WO/2017/041315
Kind Code:
A1
Abstract:
A method of designing 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 the mudflow 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. The method 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. With the method, the overall roughness coefficient n of the flume under different design conditions can be determined reasonably, 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 application of the method of designing a box-type energy-dissipating section of a box-type energy-dissipating mudflow flume.
