山区高速公路设计优化的思路和方法

Concept and Methods of Mountainous Highway Design Optimization

结合我国高速公路现状及规划建设发展趋势,从节约社会投资、降低项目建设成本角度提出了山区高速公路设计优化的概念,明确了山区高速公路设计优化的原则,分析论述了山区高速公路设计优化的思路和方法。并结合云南省大漾云高速公路设计优化实例进行了分析研究,总结了设计优化工作存在的问题,可为后续山区高速公路设计优化提供参考。

Based on the current situation of expressways in China and the development trend of planning and construction, in this paper the concept of design optimization of mountainous expressways is put forward from the perspective of saving social investment and reducing project construction costs, the principles of design optimization of mountain expressways are clarified, and the design optimization of mountainous expressways is analyzed and discussed. Combined with the design optimization example of Dali-Yangbi-Yunlong Expressway in Yunnan Province, the analysis and research are carried out, and the problems existing in the design optimization work are summarized and analyzed, which can provide a reference for the subsequent design optimization of mountain expressways.
