Abstract Research purposes: Based on the characteristic of large proportion of the elevated line in Shenzhen metro line 3, this paper puts forward several topics to be researched emphatically on the elevated line to solve the key technological issues for elevated line design.
Research methods: The paper contrasts analysis of integrated technology which will be carried out in combination with the city planning, circumjacent environment and structural system, etc.
Research results: Through the study for topics on the elevated bridge, station platform type, decreasing vibration and noise reduction, etc., this paper researches the design experiences and relative technical measures for elevated line of urban rail transit.
Research conclusions: For the type selection of elevated bridge of urban rail transit, in addition to meet the strained requirement of structure, it is also considered unitedly in combination with city planning and cityscape. Generally, the box girder is selected. For the type of elevated station platform, considering operation and mass, etc., the island platform is selected generally. For the decreasing vibration and noise reduction of elevated line the integrated measures are adopted on these aspects, such as structure, track and acoustic barrier, and so on.
