摘要
阐述了公路功能作为确定公路建设技术等级划分和主要控制指标选取的意义和依据,并探讨公路功能的特点与要求。提出以功能为主,结合地形条件、交通量参数等划分公路技术等级的方法。分析了适应于不同功能的设计车型的选取以及综合确定设计速度进行几何设计的方法,为进一步优化路网结构提供了思路。
This paper expounds the significance and basis of highway function as the technical grade division of highway construction and the selection of main control indexes,and probes into the characteristics and requirements of highway function.A method of dividing highway technical grade with function as the main factor,combined with terrain conditions and traffic volume parameters is put forward.This paper analyzes the selection of design vehicles suitable for different functions and the method of geometric design by synthetically determining the design speed,which provides ideas for further optimization of road network structure.
