摘要
山区公路山高谷深、高差大,地形地貌变化大,地质情况复杂,公路勘察设计阶段要充分考虑技术标准、行车安全、实施难度、地质条件、政策处理、土地环保、水利行洪、工程造价等各方面因素。因此路线方案的比选已经成为当前山区公路总体设计、路线设计阶段的核心内容。以330国道莲都至缙云段改建工程初步设计阶段中较为典型的几段路线方案比选为实例,阐述了山区公路路线设计方案比选的重点和要点,旨在为施工图阶段的总体设计、路线设计和工程建设阶段打下坚实的基础,其经济性、实用性显著。
Highways in mountainous area are with deep high valley,large altitude difference,large landform change,and complex geological condition.During the highway survey design stage,we should fully consider various factors like technical standard,traffic safety,difficulty of implementation,geological condition,policy disposal,environmental protection of land,hydraulic engineering and flood propagation,engineering cost and so on.Therefore,the comparison of route schemes has become the core content during the stage of overall design,route design of highways in the current mountainous area.Taking the comparison of several typical route schemes in the preliminary design stage of reconstruction engineering for the section of Liandu-Jinyun of 330 national highway as the living example,the key point and points of the comparison of route design schemes for highways in mountainous area are elaborated,so as to lay a solid foundation for the overall design of the stage of construction drawing,route design and engineering construction stage,with remarkable economical efficiency and practicability.
