摘　　要：总结轨道交通高架桥交叉口孔径布置存在的问题,研究新城的规划用地性质、人口规模、增长特征、交通特点。结合轨道交通高架线建设对沿线常规交通的影响,通过对交叉口车道通行能力的分析,得出大跨度轨道桥对交叉口车道通行能力影响有限的结论,提出轨道交通高架桥在不同级别道路交叉口的合理布跨原则。The paper summarizes span arrangement problems of metro viaducts at road intersection and studies the nature of land use planning,population size and growth characteristics,and traffic characteristics.Considering the impact of the construction of elevated rail transit line on the routine traffic,the author analyzed the traffic capacity of road intersection and concluded that large span railway viaducts at the road intersection will have limited impact on traffic.The author proposed reasonable span arrangement of rail transit viaducts for different classes of road intersections.
