基于模糊数学理论下高速公路隧道路面选型评定

摘要

以宁淮高速老山隧道工程为研究对象,综合考虑经济影响因素、技术影响因素、资源利用、行驶质量、环境保护5个隧道路面选型因子,利用二级模糊综合评价法构建了基于老山隧道的数学模型,采取专家咨询法确定了各级影响因子的权重,综合比较了沥青混凝土路面和水泥混凝土两种隧道路面类型的应用性.研究结果表明:第一层次的影响指标权值排序为技术可行性＞经济可行性＞社会影响＞资源利用.经济的增长和技术的进步成为决定路面型式的主要因素;技术可行性指标中的施工技术和原材料的性能是决定路面等级指标和质量的一个重要因素,项目的初始投资,项目是否能够按时完成并投入使用是施工过程中考虑的一个主要因素;路面质量效益直接影响到水泥混凝土路面的市场竞争和经营收益水平.%this article NingHuai high-speed laoshan tunnel project as the research object,considering the economic factors,technical factors,resource utilization,driving quality,environmental protection and so on five tunnel pavement selection factors,using the secondary fuzzy comprehensive evaluation method based on the mathematical model of laoshan tunnel is constructed,adopt expert consultation method to determine the weights of various impact factors,comprehensive comparison of the asphalt concrete pavement and cement concrete,the application of two types of tunnel pavement.The results show that the influence of the first level indicators weight sorting for the technical feasibility of economic feasibility ＞ ＞ social influence ＞ resource utilization.Economic growth and technological progress is key to the main factors of pavement type;Technical feasibility indicators is to determine the performance of pavement construction technology and raw materials in the scale and quality of an important factor,initial investment of the project,the project will be completed and put into use on time is considered a major factor in the process of construction.of cement concrete pavement in the pavement quality benefit directly affect the market competition and operating earnings level.
