灰色优选模型在高速公路路线优化的应用

摘要

高速公路路线设计的目标是保证线形指标的连续性,提供安全顺畅的行驶条件,使路线与地形和环境相协调.在长期的工程实践中,设计人员为了优化路线方案,提出了很多先进的理论和方法,并应用于工程设计中,灰色优选模型就是其中之一.本文通过介绍灰色优选模型的原理,结合设计实例,探讨了多因素影响下路线方案比选的思路.%The goal of expressway route design is to ensure the continuity of linear indicators, provide safe and smooth driving conditions and coordinate the route and topography and environment. In the long-term engineering practice, the designers put forward many advanced theories and methods in order to optimize the route plan, and applied them to engineering design. Gray optimization model is one of them. In this paper, by introducing the principle of gray optimization model and combining with the design examples, the idea of route selection and comparison under the influence of multiple factors is discussed.
