本文结合京秦高速公路天津段项目的建设,以路线所经平原路段为例,选择路线长度、地质条件、土地占用量、总投资、经济净现值、财务净现值、环境影响、路网作用,八个指标作为路线方案比选的影响因素,运用层次分析法建立数学模型对路线方案进行比选。最终找出经济合理、技术可行的最佳路线方案。 This paper, based on the construction of Tianjin section of Beijing-Qinhuangdao Expressway, takes the Plain section of the route as an example to select the route length, geological conditions, land occupation, total investment, economic net present value, financial net present value, environmental impact, road network Role, eight indicators as the route selection and comparison of the influencing factors, the use of analytic hierarchy process to establish a mathematical model to select the route program. Ultimately find out the most reasonable and technically feasible route plan.
