摘要
A debris flow drainage trough planning and designing method comprises the following steps: determining the total length L of a proposed drainage trough and the longitudinal gradient of a drainage trough gully bed; determining the full lining trough type of an inlet section (1), the length L1 of the inlet section (1) and the included angle α between a side wall and a main trough of the inlet section (1); determining the full lining trough type of an outlet section (4), the length L4 of the outlet section (4) and the included angle β between a side wall and the main trough of the outlet section (4); determining the full lining trough type of an acceleration section (2) and the length L2 of the acceleration section (2); and finally, determining the trough type of a main trough section (3) and the length L3 of the main trough section (3). The method provides high drainage efficiency, makes siltation avoided, provides effective protection, and needs low cost. Also disclosed is an application of the designing method.
