| Abstract: | Based on the 3rd phase expansion project of Shanghai Pudong International Airport Rapid Transit and combined with the characteristics of airport rapid transit system,the main schemes of track structure design are introduced.Through expounding the key and difficult engineering points,effective solutions to the track structure design are proposed,including diversified vibration and noise reduction measures,fine design of multi-party linkage,long-distance ultra thin monolithic track bed without sleeper,and large line spacing floating slab turnout.Finally,optimization suggestions and considerations for the of track structure design are proposed,including the application of precast slab,drainage scheme of floating slab track bed in flat slope section,and additional noise reduction measures. |
