模糊数学在山区公路建设初设阶段方案比选中的应用研究

在山区公路建设中，初步设计阶段常遇到多方案比选问题。由于影响方案取舍的因素较多，定量分析难度大。基于模糊数学的方案比选法是一种半定量评价法，该法将多种因素对方案影响的不确定性转换为确定性，可克服多因素的模糊性影响，并在项目建设中或建成后对比选结果进行量化验证。以新普公路与成雅高速公路交叉工程为例，应用模糊数学对该项目进行方案比选研究。

Research on Fuzzy Mathematics Applied in Comparison and Selection of Plans at Preliminary Design of Highways in Mountainous Area

In construction of highways in mountainous area, the preliminary design stage often faces comparison and selection among multiple plans. Since there are many factors influencing the acceptance and rejection of plans, it is difficult for quantitative analysis. The comparison and selection method of plans based on fuzzy mathematics is a semi-quantitative evaluation method, which transforms the uncertainty of multiple factors influencing plans into the certainty so as to overcome fuzzy influences of multiple factors, and makes quantitative verification on results of comparison and selection during construction or after completion of projects. With the cross construction of Xinpu Highway and Chengya Expressway for example, this paper researches on comparison and selection of plans for the project by means of fuzzy mathematics.
