摘要
前曹公路是上海市嘉定区北部一条南北向一般公路,随着规划罗蕰河和新川沙河的扩宽改造,前曹公路桥将拆除重建。该桥规划桥位位于两条河道交叉口处,考虑到河口位置处建桥桥梁主跨较长,可能存在不经济性。因此,对沿线现状及规划进行梳理,分析前曹公路桥建设的必要性,对交通流量预测并确定车道规模,对桥梁平面线位进行多方案比选,从而推荐出合理的桥位方案。
Qiancao Highway is a north-south ordinary highway in the north of Jiading District in Shanghai.With the planned widening reconstruction of Luowen River and Xinchuansha River,the Qiancao Highway Bridge will be demolished and rebuilt.The planned position of this bridge is located at the intersection of two rivers.Considering that the main span of the bridge is long at the outlet of the river,it may be uneconomical.Therefore,the present situation and planning along the line are sorted out.The necessity of the construction of Qiancao Highway Bridge is analyzed.The traffic volume is forecasted and the lane scale is determined.The multiple schemes of the bridge plane alignment are compared so as to recommend the reasonable scheme of bridge alignment.
