Abstract:

The technology of V-shaped draining and diverting grooves has been used in preventing and curing mud-rock flows in Yunnan since 1990, about 30 mudrock flows have been cured by using this technology, and it has been practiced and summed up. This paper mainly focuses on an introduction of the features of mud-rock flows of Yunnan, the theory basis of V-shaped grooves and the technological achievement of preventing and curing mud-rock flows by spreading this technology.

Key words: mud-rock flow, V-shaped draining and diverting groove, application
