Research On Hazard Classification And Dynamic Design Of Mountainous Highway High Slope

Recently the construction of highway is in the ascendant in our country.During the construction of highway in mountainous areas,the high cutting slope is often encountered,and its stability can directly affect the safety of construction and operation of highway engineering.Once the high slope occurs the accidents,it will cause economic and social effects or threaten the safety of life and property,and it can be unbearable to contemplate the consequences.For the high slopes in mountainous areas,what contents of the dangers,whether they need reinforcement,which methods should be used to reinforce them and how about the effect of reinforcement,are the questions that the construction personnel keenly want to know and the researchers keenly want to research.There are many factors that affect the safety of the slope,and the relationship between them is complex,and the direct object of this problem is to give a persuasive judgment standard.This paper used the related ideas of analytic hierarchy process,and worked out the weights of all kinds of influential factors,and combined with the author’s many years of experience,the evaluation indexes of 16 high slope engineering risk factors(to be divided 4 classes)were given,what’s more,the risk classification standards were given,so that the question can be solved quantificationally.The discovery can directly serve the project construction,overcome the disadvantages of the current "one size fits all" approach,and can make full use of the relevant engineering geological information of enterprise.About dynamic design of high slope,based on the left slope of ZK227+600 ~ +770 section of Shuangyong highway,protocoled the treatment scheme which referred to the relevant report and the standard,this paper demonstrated the rationality of the dynamic design method with the actual engineering measures,meanwhile,for the slope,with the help of GEO-SLOPE limit equilibrium software,the treatment scheme of the slope was completed based on the numerical simulation.Above two researches,respectively from the points of views of dynamic design and information construction,studied the high slope of the highway,and its research ideas and methodology had a very good reference for the design and construction of high slopes.
