宜昌市港窑路工程选线研究

Study on Line Selection of Yichang City Gangyao Road Project

依托宜昌市港窑路工程,针对山岭丘陵区特殊的地貌,按照"宏观到微观"的思路,从线路走廊带的选择,到确定线路沿线的主要控制点,结合沿线不同的建设条件进行分区段地形选线及比较。按照"分段选线、择优组合"原则,系统地阐述了山岭丘陵区道路选线的研究过程。

Relying on Yichang City Gangyao Road Project,aiming at the special landform of mountainous hilly area,according to the concept of 'macroscopic view to microscopic view',from the selection of line corridor zone to the main control point determining the route along the line,and combined with the different construction conditions along the line,the lines are selected and compared by the sectional terrains.According to the 'sectional line selection and preferential combination',the article systematically sets forth the study process of road line selection in the mountainous hilly area.
