Discussion on the Railway Route Selection in Guangdong-Hong Kong-Macao Greater Bay Area
Research purposes:The development of the Guangdong-Hong Kong-Macao Greater Bay Area is an important national policy in China,and railway transport is an important infrastructure for regional development.The regional economy is developed,the urbanization degree is high,the railway direction is restricted by many factors,and the route selection is difficult.This paper summarizes some railway route schemes in the Bay Area,summarizes the important and difficult points of railway route schemes in developed areas,and puts forward countermeasures and principles.Research conclusions:(1)Technical standards such as reasonable speed target system should be determined according to different functions and construction conditions of railway lines;(2)Urban built-up areas reduce the impact on the city,use tunnels and bridges to lay lines along road passages,make intensive use of land resources,and conform to urban planning;(3)In the urban area are dense,deepen the design of work points and reasonably determine the spacing between railways and various structures;(4)Appropriately increase the proportion of bridges and tunnels;(5)Fully develop the underground space through innovative station design;(6)The research results can provide reference for railway route selection in urban agglomeration.
