Research And Analysis On The Railway Diseases Of High Speed Railway Passenger Dedicated Line

The line is composed of passenger dedicated line most important infrastructure in the structure,the high speed train running safely and stably on line protection.In the change of external environment,line equipment will be greatly affected,it will appear a variety of railwaylinediseases,these diseases will not only influence lines of the overall quality,will greatly reduce the safety of train operation,there are some diseases and even cause serious traffic accidents,greatly restricts the development of Passenger Dedicated Line;Therefore,we must use advanced technical means to strengthen the maintenance work of the line.At the same time,also need to in-depth research and analysis for the disease,to find out the relationship between the incidence of the disease causes and diseases.In view of the disease puts forward feasible solutions,in order to ensure the quality and driving safety line.The paper mainly discusses the following three aspects:(1)To set the Ji Bao of passenger dedicated line as an example,through the track inspection car collected relevant data of 18 months,and statistical analysis of the data,identify appeared in the line focus of disease type and location,and judge the degree of development of the disease.Using TQI value of the line uplink K251-K305 km section of the overall evaluation of the track quality.(2)Ji Bao passenger dedicated line for ballast track,according to the data of the track inspection car line to find disease,and analyzed for types,causes,treatment methods and how to prevent the disease.In addition,there are also some common track other diseases make a review and summary of the high-speed railway,and puts forward some feasible solutions.(3)With the vigorous development of ballastless track in our country,the passage about on ballastless track common diseases are analyzed at the same time.The development of ballastless track is not very mature,although the theoretical support,but also need to explore.Ballastless track common disease mainly present in the track structure,the track structure is mainly composed of reinforced concrete materials,it's different with the traditional ballasted track,and the type of disease treatment is also different.Analysis of ballastless track meet maintenance diseases to track maintenance division,focus on how to repair after the disease.
