Abstract
An asymmetric debris-flow discharge channel is provided. The debris-flow discharge channel has a main drainage channel for discharging a debris flow and an auxiliary channel provided outside of the main drainage channel. The side walls of the auxiliary channel are integrated with the side walls of the main drainage channel or provided outside of the side walls of the main drainage channel. The debris-flow discharge channel also has a break section integrated into a side wall of the auxiliary channel. The top width of the break section is equal to the top width of the auxiliary channel A method for designing and building the asymmetric debris-flow discharge channel is also provided, which provides a lower initial cost, higher safety performance, and a lower maintenance cost at the operating stage.
