Study On Optimization Decision For Mountainous Highway Slope Disease Treatment

With the development of mountainous highway construction, disease problems ofhighway slope is also becoming more and more.For many alternative treatment schemes,it is difficult to accurately decision-making method to control the ideal treatmentschemes. So we need to further research all kinds of slope treatment technology, and thecontrast analysis, in order to selectively be used in actual engineering, and proposing anoptimization method of the slope treatment for improved decision-making, make theslope treatment become more scientific and reasonable.The main contents of this paper are as follows:â‘ First of all, understand the influencing factors of slope stability, then introduce thedestruction forms and the disease types of the highway slope, the key is to introducecontrol measures of highway slope, including slope rate method, drainage, protection,retaining wall and reinforcement measures, mainly study the mechanism, advantagesand disadvantages of various techniques, adapting to the conditions and the status of theapplication and so on.â‘¡Secondly, in view of decision-making on slope treatment schemes, this chaptermainly introduces the method of experiential discriminantion, analytic hierarchy process,the decision-making of fuzzy multiple attribute and the subjective and objective method.The method of experiential discriminantion is a traditional decision-making methodused frequently in the actual, but it is a rough way to judge, which has many uncertainfactors, can not be more accurate to give a slope treatment scheme. Although analytichierarchy process, the decision-making of fuzzy multiple attribute and the subjectiveand objective method have their advantages and disadvantages, but combining threemethods, you can propose an improved optimization decision-making method of slopetreatment schemes.â‘¢Then, First of all, from the research of the current slope treatment schemes, Ianalyze the influencing factors of selecting slope treatment schemes, then put forwardthe evaluation index system of improvement of slope treatment schemes optimization, toprovide the basis for slope treatment schemes optimization, the evaluation index systembasically reflects the influencing factor of the various aspects of the slope treatmentschemes performance, finally from the fuzzy multiple attribute decision-making theory,the combination of AHP and DEA method is used to determine the weights of evaluation indexes, set up the decision-making and evaluation model of slope treatmentschemes optimization, come to the sort method of the slope treatment schemesoptimization. The improvment decision-making method of slope treatment schemes ismainly the improvement of the evaluation index system and the improvement of theweighting scheme.â‘£Finally, combining with the disaster management engineering of the S103YunYangK360to K380of Chong Qing and slope engineerings of Manhattan to actualengineering test slope treatment technology as well as the application of managementdecision-making method.
