Abstract

Rail transport as an economic,efficient,safe,and efficient modes of transport,has become widely used at home and abroad forms of transport.The stability of the track structure,the maintenance workload,and can better adapt to the needs of modern society of people and goods of high-density transport,so the vast majority of cities and urban transport options for the rail transport.At present,China's railway rail transport is in the rapid construction and development period，and its very broad application prospects.In this paper,an extensive literature survey on the basis of the new track structure as the main object of study,starting from the concept of the system,combined with China's national conditions and road conditions,consider its study.

City rail structure structure and high-speed rail track structure,combined with scientific research and development in recent years,from the drawings,for example,form comparison,as well as text Summary of its characteristics,track fasteners,construction techniques to do the analysis and explore.

In the stage of large-scale construction of urban rail transit,rail traffic generated by the vibration and noise pollution also caused widespread concern.Vibration and noise problems for the superstructure of the Shenzhen Metro on the 5th line Tanglang Depot,Depot track vibration and noise sources,as well as vibration and noise values predict the outcome of a variety of damping and noise reduction measures compared to the light of local conditions depot track vibration and noise reduction measures,so that the vibration and noise of the trains running on the superstructure to meet environmental requirements.

Keywords: urban rail high-speed railway track structure track fasteners
