Study Of Debris Flow Prevention And Control In Daocheng County Ganzi Sichuan Province

Debris flow is a common geological disaster in the mountainous area, which accounts for 2/3 of the land area, and is one of the countries with more extensive distribution of debris flow disasters and more serious disasters in the world. The prevention and control of debris flow disasters in China are mainly concentrated in the middle of the last century, urban construction, water conservancy and hydropower, transportation departments respectively to the domestic large debris flow disaster of governance, accumulated a lot of experience for the prevention and control of debris flow disasters in China, making the debris flow disaster prevention and control technology is increasingly mature.The research object of this paper is located in Daocheng County, Ganzi Prefecture, Sichuan province surrounding, Daocheng County on the south side of the sub Luo Gou, Department of transportation by the back flush ditch and substation behind the gully and so on three ditch surrounded by range gully area of the sum 10.1km2. Main distribution area of debris flow accumulation.The previous studies after in the region visited and investigated by drilling, pitting exploration means, combination of laboratory test results, that the debris flow for rainstorm slope erosion type high-frequency deluted debris flow gully, in recent years the government records, the debris flow every year, there are varying degrees of, serious harm to the local people’s life and property safety.According to the type of the research object, this paper puts forward two governance options, select a more reasonable scheme to control, and achieve the purpose of disaster prevention and reduction.
