摘　　要：山渣料具有一定程度的风化，岩性、颗粒组成及含水量等存在很大的变异性，公路建设采用山渣料填筑路基，横断面设计偏于保守。综合考虑路基的稳定性、抗冲刷性和经济性，提出了综合赋权多属性决策模型，建立了适合公路路堤横断面设计的优化方法，利用综合赋权多属性决策优选模型对山渣料高路堤横断面的设计方案进行优选，在稳定的前提下优选出最为经济的方案。该方法具有概念清晰、计算方法简单，提高决策精度等特点，并减少了主观赋权和客观赋权的影响因素，为横断面最优设计形式的确定提供了理论依据。Earth-rock mixture has certain decency degree, the litho logical character, the granulometric composition and the water content and so on , exists very huge changeability, the highway construction uses Earth-rock mixture as the reclamation for roadbed, and the design of the cross section is conservative. According to the overall evaluation of the stability, the anti-washout and the efficiency of the roadbed, the synthesis bestows on the power multi-ob- jective decision making model is proposed, and then the optimized method of the road embankment transect is established, and the model of the multiple attribute decision making of combination weights is used for choosing the optimal plan for design of the high embankment transect of earth-rock mixture. This method has the characteristics of clear concept, the simply computation, and increases policy-making precision and so on, and reduced the influence of the subjective and objective power factors, then the theory basis is provided for the most superior design of transect form.
