摘要

 
    

The Sichuan “5.12” great earthquake seriously damaged local geological environment and brought about many places of geological hazards. This paper analyzed formation mechanism, distribution, natures and features of flood-ditch mud-rock flows in the earthquake-hit areas, measured and estimated reserve of solid material source, made a calculation in detail of nature parameter of mud-rock flow, conducted design calculation for preventive and treatment works, and finally put forward the key points in design based on example works and experience.
