山区高速公路路线设计探讨

Discussion on Route Design of Mountain Expressway

通过对山区自然、地理、地质条件等控制因素的分析,归纳总结了山区高速公路路线设计的基本原则,重点分析了山区高速公路路线设计中应重点研究的安全、环保、经济等因素,论述了山区高速公路路线设计中设计标准的掌握、平纵面设计指标的具体选用以及与地形、环境的协调和配合,提出山区高速公路路线设计应从初期的平纵协调,进一步深化为平纵横相互协调和相互优化,以满足山区特殊地理、自然环境和公路工程建设本身的要求。

Through the analysis of the natural,geographical,and geological conditions in mountainous areas,the basic principles of highway route design in mountainous areas are summarized.This paper focuses on the analysis of safety,environmental protection,economic and other factors that should be studied in the design of mountain expressway routes,and discusses the mastery of design standards in the route design of mountain expressways,the specific selection of horizontal and vertical design indicators,and the coordination and cooperation with terrain and environment.It is proposed that the highway route design in mountainous area should be further deepened from coordination between horizontal and vertical to mutual coordination and optimization among horizontal,vertical and transversal,to meet the requirements of the special geography,natural environment and highway construction in mountainous areas.
