摘要
根据国道108线砂河-神堂堡段工程可研报告的设计,针对山岭重丘地形条件复杂的情况,就设计主要技术参数的选定和计算方法、路线布设与地形条件的合理结合、路基、路面的设计、主要技术指标如平曲线、竖曲线半径、最大纵坡及坡长采用等进行了分析和比较,较为合理的利用了地形,对环保、水保等进行了综合考虑,既使设计可满足使用条件,又最大限度节省了投资,具有好的使用价值,为山岭重丘区一级路设计提供了可借鉴经验。
According to State Road 108 line Sand River-Shentang Fort section of the design feasibility study report for the conditions,the mountainous terrain complicated the situation,the main technical parameters of the selected design and calculation methods,routes and terrain conditions laid reasonable combined,roadbed,road design,the main technical indicators such as flat curve,vertical curve radius,the maximum vertical gradient and slope length were analyzed and the use of such comparison,a more reasonable use of terrain,environmental protection,water conservation,etc.were taken into account,not only make the design can meet the conditions of use,but also to maximize savings in the investment,with good value,as the experience that can draw lessons from for mountainous area level road design.
