The Hazard Assessment For Highway Debris Flow

The western mountains of china is a concentration of Debris Flow.It is not possible for the road traffic inevitably across the Debris Flow. Line often through the complex geological environments high-relief background, and the climate conditions of terrain.The Debris Flow in this areas is easy-happening. The disaster area are often interrupt the traffic, take a heavy toll. Into hiding, chuan dian, and chuanshan,ganchuan for connection to china's tibet, yunnan, sichuan, gansu and been waiting for the western road traffic, the disaster was particularly prominent. Therefore strengthen the disaster that the risk assessment studies are important theoretical meaning and value.This research depends on the line G212 longnan g213 dongchuan g217 line dukuzi—kuche,finally give the harzed Assessment For highway Debris Flow.The first to the formation conditions, this disaster, distribution, the harm done with. to the concept and connotation of the elaborate comprehensive analysis of all kinds of danger. evaluation methods of research in this paper studies to determine the method of study based on in-depth analysis. the vague complex.The opinion of the dangers from three levels in research, culture, sections, a study.(1) Regional research mainly on the flow of the dangers of ownership is an area likely to the extent of the danger area out and the dangers of the review content.(2) Sections of the study for a certain sections of the danger, it is in danger of the evaluation dangou, a certain sections of the development of environmental analysis, comprehensive survey in detail the effect of factors, choosing reasonable mathematical method determines a certain sections of the danger level, it was both dangerous and the new highway the appraisal target system for major construction of highways reference.(3) For a typical the possibility of evaluation is on the detailed survey dangou on the basis of evaluating the number or mark the evaluation of the mathematical method to determine the form of a dangerous level, dangou the dangers of the opinion of the indicator system.
