摘要
城市道路快速化改造在选择建设形式时,会受各种影响因素的制约。以襄阳市内环线提速改造二期工程中的北线西段为例,在流量预测的基础上分析建设规模,筛选出可行的快速路改造模式。分别阐述“高架式”与“地平式”2种建设方案的设计过程,重点比较2种方案对现状条件的适应性,明确推荐结论。最后总结出城市道路快速化改造应贯彻“科学适用、因地制宜”的指导思想。
When choosing the construction form of urban road rapid transformation,it will be restricted by various influencing factors.Taking the west section of the north line of the innerring speed-up reconstruction phase Ⅱ project in Xiangyang as an example,the construction scale is analyzed on the basis of flow prediction,and the feasible expressway reconstruction mode is selected.The design process of elevated and horizontal construction schemes is described respectively,focusing on the comparison of the adaptability of the two schemes to the current conditions and clarifying the recommended conclusions.Finally,it concludes that the rapid transformation of urban roads should implement the guiding ideology of scientific application&adaptation to local conditions.
