S型河曲段高速公路的优化设计

The Optimization Design of S Meander Section of Highway

通过对某高速公路河曲段的原设计方案的缺陷分析,阐述了山区高速公路在设计的过程中应考虑的制约因素,包括工程造价、施工工期、施工方案、施工组织、环境保护、排水防汛、地方发展规划等等。针对性地提出了优化方案,通过对优化方案的阐述,体现了综合考虑、系统分析、全周期设计在复杂工况设计中的重要性,为以后的山区高速公路设计提供参考。

Through the defect analysis of the original design of a highway meander section,this paperexpounded the factors should be considered in the design process of mountainous area highway. It also put forward the optimization scheme, which provided the reference for later highway design in mountainous area.
