摘　　要：随着城市的更新发展,路网的完善对于改善交通问题显得至关重要,跨越铁路、河道的道路建设必不可少,可有效加强两岸的沟通与联系。跨铁、跨河道路方案设计时会面临行人及非机动车通行、两侧交通转换方式、桥梁布置形式、涉铁净空等一系列问题。现以南阳市张衡西路跨焦柳铁路工程为例,综合分析了功能定位、交通现状、用地状况、工程造价等因素,对三个总体设计方案进行了详细比选论证,最终确定了安全、环保、节约、美观的推荐方案,为今后同类城市主干路总体设计方案比选提供参考。With the renewal and development of city,the improvement of the road network is very important for improving the traffic problems.The road construction across the railway and river is essential,which can effectively strengthen the communication and contact between the two sides.The design of road scheme crossing the railway and river will face a series of problems such as pedestrian and non-motor vehicle traffic,traffic conversion mode on both sides,bridge layout,and clearance involved to railway.Taking the project of West Zhangheng Road crossing Jiaozhou-Liuzhou Railway in Nanyang City as an example,the functional positioning,traffic status,land use status,engineering cost and other factors are comprehensively analyzed.Three overall design schemes are compared and demonstrated in detail.Finally,the recommended scheme of safety,environmental protection,economy and aesthetics is determined,which provides a reference for the comparison and selection of the overall design schemes of similar urban trunk roads in the future.
