张家界武陵山大道拓宽改造工程总体方案设计

由于城市架构层层扩张,交通压力不断增大,因而需对既有道路进行拓宽改造.以张家界市武陵山大道(张清公路)拓宽改造为工程实例,介绍其建设背景、项目概况和主要技术标准.通过对工程交通流量的预测和规模的论证,对工程总体方案进行了研究.根据不同路段的功能情况对子午路(起点)至县道X018(终点)中4个路段的横断面型式进行了分别布置;在充分考虑与周边地块进行衔接的基础上,对大学城高架节点等4个节点进行了设计.最后总结强调,项目在设计过程中,在满足道路畅通的同时,还要充分考虑地方规划、现状条件、挖填平衡、不同路段的功能和周边地块情况,以完善区域路网结构,带动沿线经济发展.

Design of Overall Scheme for Zhangjiajie Wuling Mountain Avenue Widening Reconstruction Project

The traffic pressure is building up because of urban framework expansion continuously. Therefore, the existing roads are required to widen and reconstruct. Taking the widening reconstruction of Wuling Mountain Avenue (Zhangqing Highway) in Zhangjiajie as an engineering case, its construction background, project overview and main technical standards are introduced. Through the prediction of engineering traffic flow and the demonstration of scale, the overall scheme of the project is studied. Based on the functions of the different road sections, the cross-sectional patterns of four road sections from Ziwu Road (starting point) to the county road X018 (end point) are arranged respectively. On the basis of fully considering the connection with the surrounding lands, four nodes of University Town Elevated Bridge are designed. The summarization shows that the local planning, present situation, excavating and filling balance, functions of different road sections, and situations of surrounding lands are also fully considered in the design process of the project and at the same time to meeting the smooth traffic in order to perfect the regional road network structure and drive the economic development along the line.
