摘要
为了保证公路行车安全,文章首先分析了公路路线设计的原则,随后以越岭线、沿河线为例,分析了公路选线注意要点.最后,从直线长度、平曲线半径和转角、回旋线长度、纵坡坡度等方面分析了路线平、纵指标选用及组合的注意要点,研究成果可供公路路线设计借鉴.
Abstract
In order to ensure the safety of highway driving,this paper first analyzes the principles of highway route design,and then analyzes the key points of highway route selection by taking the ridge crossing line and the riverside line as examples.Finally,the key points for selecting and combining horizontal and vertical indicators of the route are analyzed from the aspects of straight line length,horizontal curve radius and corner,clothoid length and longitudinal slope gradient.The research results can be used as reference for highway route design.
