摘要
四川"5.12"大地震,严重的破坏力当地的地质坏境,诱发多处地质灾害。本文对地震灾区洪水沟泥石流形成机理、分布状况及性质特征进行了分析研究,实测和估算出固体物源动储量,详细计算了泥石流流体性质参数。进行了防治工程设计计算。结合工程实例及实践经验,提出了泥石流防治工程设计要点。
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 rpeventive and treatment works,and finally put forward the key points in design based on example works and experience.
