Viscous debris flow rectangular drainage groove depth measuring and calculating method and application
The invention discloses a viscous debris flow rectangular drainage groove depth measuring and calculating method and application. According to the method, the influences of the debris flow volume weight, the debris flow solid matter grading, the ditch bed gradient and the mud depth on the flow velocity of viscous debris flow are fully considered, and a viscous debris flow mean velocity calculation formula with high applicability is established based on statistical regression of a large quantity of observation and exploration data, and then the design depth of a rectangular drainage groove for the viscous debris flow can be determined by combining the design width of the drainage groove and the design flow of the drainage groove on the design conditions and considering the free height of the drainage groove. The method can provide effective technical support for optimal design of the rectangular drainage groove for the viscous debris flow and meet the practical engineering requirements.
