| Slope as an important component of the road, road slope prevention is playing an important prevention in the overall level of road play.Through the slope protection, not only can get a solid foundation, but also can get a more beautiful road capacity.In this paper, the article based on different types of slope protection, using of Analytic Hierarchy Process theory, principles and methods established an Evaluation Index System for Slope Protection. slope protection can not only provide a theoretical basis for decision-making, but also for future highway slope protection to provide decision-making methods.The system includes four criteria layer,11 indicators and 25 variables layer, and can evaluate the main function of slope protection, the ecological benefits, economic benefits and social benefits. the article based on the quantitative and qualitative analysis for the 25 variables, with the expert evaluation and weighted calculation, calculated the benefits of road slope protection value. Duing to the result of evaluation, this paper analyzed the existing factors of the slope protection decision and established slope protection decision-making system. The system includes slope stability, slope protection measures suitability, the technology situation of slope protection and benefit of the slop protection. The establishment of this system further improved the investment decision-making theory of slope protection.Taking a typical highway slope protection of the Arid and semiarid zone road for example, this paper proposed 6 types slope protection methods, used the slope protection evaluation system to analysis these slope protection methods and reached the following conclusions. The effectiveness of road slope protection is Grass Geocell Protection and the guest earth Broadcasting Technology.; followed is Three-dimensional Vegetation Protection and Grassing in the Mortar Rubble network Backbone Protection; the last is Grass Planting and Protection the Mortar Rubble net-work Backbone Protection. |
