衡水北枢纽互通改扩建方案设计

Reconstruction and Expansion Scheme Design of Hengshui Northern Pivot Interchange

衡水北枢纽互通,原为衡小高速与衡德高速交叉处互通,后大广高速修建时对此互通进行了改造,保留了原互通匝道,在大广高速公路上加设两条定向匝道,分别完成德州-衡水方向及衡水-北京方向交通流转换。新建邢衡高速需再次对该互通进行改造,通过本互通完成邢衡高速、大广高速的交通转换。详细介绍了此互通改造方案的比选方案。

Hengshui northern pivot interchange is the interchange at the junction of Hengxiao Expressway and Hengde Expressway formerly.Later,the interchange is reconstructed when Daguang Expressway is built,and the original interchange ramp is maintained.Two directional ramps are built on Daguang Expressway,respectively realizing traffic flow conversion in direction of Dezhou-Hengshui and Hengshui-Beijing.Reconstruction is made again due to new establishment of Xingheng Expressway,realizing traffic conversion of Xingheng Expressway and Daguang Expressway.The comparison and selection scheme for reconstruction scheme of this interchange is introduced in detail.
