| Abstract: | 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. |
