Abstract


The highway slope as an important part of the road , slope protection is important highways play a role in the overall level of protection . Slope protection , not only a solid roadbed , beautify the road capacity and can play a role . In this paper, the different types of highway slope protection , theories, principles and methods of using the analytic hierarchy process to establish a set of effective slope protection effective evaluation system can not only provide a theoretical basis for the slope protection decisions for future highway slope protection decision-making method . The system includes four criteria layer 11 index layer and 25 variable layer , and the evaluation of the transport function of slope protection , ecological benefits , economic benefits and social benefits . Based on quantitative and qualitative analysis of 25 variables layer , obtained by expert assessments and weighted calculation of the effective value of the highway slope protection . Highway slope protection benefit evaluation based on the analysis of the existing slope protection decision influencing factors , including slope stability , slope protection measures suitability , slope protection measures and technical conditions and slope protection benefits the slope protection decision - making system, improve the investment decision-making theory of slope protection . A semi-arid areas of Northern Expressway typical slope protection , for example , six kinds of highway slope protection programs , and these programs take advantage of the slope protection effective evaluation system analysis , and reached the following conclusions : on the road grass protection and Spraying of Geocell slope greening slope stability case for the benefits of the semi-arid areas of highway slope protection protection optimal ; 3D vegetation net protection and mortar rubble skeleton grass protection followed ; grass protection and mortar rubble revetment protection is the worst .
