公路多方案研究、论证和比选是合理确定路线方案的前提,是公路总体设计的关键.针对山区地形的特点,根据山区公路选线的基本原则,建立了山区选线方案的评价指标体系,并求解出了各评估指标的权重,借助模糊数学理论,建立了基于多目标决策的山区公路选线优选模型,提高了解决山区选线问题的科学性.以某山岭重丘区二级公路的选线问题为例进行了分析和计算,验证了基于多目标决策的山区公路选线优选模型的合理性与有效性,证明了该模型在实际应用中具有较强的可行性.
Highway multi-program research, demonstration and comparison are the preconditions for rationally determining the route scheme and are the key to the overall design of the highway.According to the characteristics of mountainous terrain, the evaluation index system for mountain route selection scheme is established according to the basic principles of mountain highway route selection, And the weight of each evaluation index has been solved. With the aid of fuzzy mathematics theory, the optimization model of mountain highway route selection based on multi-objective decision-making has been established and the scientific problem of route selection in mountain area has been improved. This paper analyzes and calculates the problem of line selection, verifies the rationality and effectiveness of the optimization model of mountain highway route selection based on multi-objective decision-making, and proves that the model is more feasible in practical application.
