摘要
为合理高效地解决公路线路方案综合比选问题,开展了基于改进密切值法的高速公路选线方案研究。首先在考虑多维因素影响的基础上建立优选评价指标体系,并运用CRITIC法和灰色关联法分别进行指标权重计算,其次基于卡方距离组合赋权法确定最优组合权重,最后统筹线路工程信息和改进密切值法实现线路方案优选。研究结果表明:通过构建简洁有效的评价指标体系,运用组合赋权方法确定最优权重,结合改进密切值法进行指标的合理化表达和方案优劣分析,其判定结果与专家实际论证情况相一致。该优选方法提高了公路线路方案优选的科学性和适用性,研究结果可供高速公路线路方案优选参考。
To solve the problem of comprehensive comparison and selection of expressway route schemes reasonably and efficiently,the research on expressway route selection scheme based on improved osculating value method is carried out.On the basis of considering the influence of multidimensional factors,the optimal evaluation index system is established.The CRITIC method and the grey correlation method are used to calculate the index weight respectively,and the optimal combination weight is determined based on the chi-square distance combination weighting method.Finally,the route project information is coordinated and the improved osculating value method is used to realize the line scheme optimization.The results show that the K6 scheme is superior to the E5 and E1 schemes,and the judgment results based on this method are consistent with the actual demonstration of experts.This optimization method improves the scientificity and applicability of expressway route scheme optimization.The research results can provide some reference for the optimization of expressway route schemes.
