COMPARISON FOR ADMINISTRATION MEASURE OF DEBRIS FLOW AT SANYANYU GULLEY

Debris flow occurred on August 8,2010 at the Sanyanyu Gulley and Luojiayu Gulley,Zhouqu County,Gansu Province caused the county a big loose of both lives and properties.Based on the＂8·8＂ debris flow disaster happened in Zhouqu County and the management engineering design project,four aspects of the difficulty of the project,investment,safety and service fixed number of year to argue the type of the dam.At the same time,three aspects of the project investment,covers and safety to argue The row of the platoon guide canal.Selecting reinforced concrete dam and taking the way straight section benting in the original basis to built the canal as the optimal treatment measures.The application of measures provides the reference for the selection of design scheme at the similar projects geological conditions of the disaster management engineering.
