Study On Treatment Technique And Scheme Decision Of Slope Disease Of Mountainous Highway

With the further accelerating of mountainous highway construction, more and moredisease problems of highway slope need us to transact, and the existing specificationshave not completely meet high or large and complicated slope treatment project;Meanwhile, facing the more selectable treatment scheme, it is difficult to objectivelyand scientifically make a strategic decision for its good or bad. Therefore, we need tosystematically research various treatment techniques of slope, and comparativelyanalyzing and inducting and summarizing various technical index of the treatmenttechnique of slope about their respective advantages and disadvantages and applicabilitymechanism and applicability in practical projects, etc. It is intended to could selectivelyuse in the slope treatment project and select the best scheme decision-making method tomake a successful treatment more scientific and reasonable.This paper is based on a lot of investigation and practical engineering experience,having a deep analysis and systematically induced to the existing treatment technique ofslope, researching of highway slope classification, characteristics of treatment techniqueof slope and decision-making method of the treatment scheme of slope. They are usedin the practical engineering example.The main contents of this paper are as follows:Firstly, combined with characteristics of highway slope, it will have areclassification for slope, respectively according to the height and slope of slope, thestability state of slope, the body composition of slope, the engineering geologicalcondition of slope, the rock mass structure and failure mode of slope.Secondly, highway slope treatment measures are divided into slope-rate method,drainage, protective method, retaining method and reinforcement method. And toresearch every characteristics of measures for the practical treatment technology in theproperties, mainly studies the function mechanism of treatment technology, advantagesand disadvantages, adapt to the conditions and application status of technology index.Thirdly, according to decision-making method of the treatment scheme of slope,giving the need to collection material content, and introducing two traditional decisionmethods, and mainly studying two mathematical model decision-making methods, thussolving the difficult problems about decision-making method of the treatment scheme of slope with influence by various factors.Finally, combining with Chongqing YunYang Qingliang Changping slopeengineering and Chatian landslide engineering, application of treatment technique andthe decision-making method of the treatment scheme of slope will be tested by practicalengineering.
