Abstract After speed-raising of the existing railway line， train on the track impact damage increased， on the track structure of the increasingly high demand， to track the service life and the daily maintenance and repair work to bring a lot of To compensate for the current speed situation and actual equipment didn't match the inadequacy， must constantly improve the inspection， repair and strengthening the thinking way of the basic This paper around the speed-raising of the existing railway line equipment on later revealed the problem， from the curve， turnout， seamless line and how to punish the swing of locomotive is discussed from four aspects such as， should say covering the main The disease causes of repeated discussion and analysis， summed up the measures， through the field practice and achieved certain Key words: speed-up section Track Disease Analysis of the reasons Treatment measures
Abstract: the paper analyses the existing in the railway roadbed disease are classified， analyzes all kinds of railway roadbed disease occurs， this paper introduces the mechanism of roadbed disease detection method， and points out that the various types of clear roadbed disease and formation mechanism， and the accurate detection is railway roadbed disease prevention and effective governance Article embankment is band structure engineering， the geological conditions along through the difference is bigger， packing is also not even， and many areas in expansive soil， the red clay， soft rock weathering residual soil underlying engineering properties of soil， and the bad by geography and climate change affects， and because of all the technical level， economic conditions and the construction of the reasons of the mechanical equipment， China's railway roadbed design usually adopts low technical standard， the construction quality often lax， leading to various requirements of railway and become a bed disease wide distribution， management difficult， multiple strong disease， and in recent years with the speed of the train and heavy of subgrade stress level， Distribution condition and functions of the significant Because both railway roadbed design capacity， train speed in smaller after the dynamic stress caused by load under various diseases， leading to produce， or make already existent diseases more serious and the serious influence the safety operation of the So understand the type of disease and its occurrence mechanism， and carries on the practical detection， the protection and management of subgrade is very Keywords: railway roadbed， disease， mechanism， detection
At peak hours， to take the train from the rear yard line to turn back legislation to line Start time because of work 7 minutes， start in the compact (3 minute interval) cases must be made to take up 4 lines， will be made to Unit 4 in the first half for the start line， the second half 3 shares issued to the line for vehicle access (As the final 6 minutes of time to work， only three lines can not be made to access 3 minutes interval in a row to reach the train) In the off-peak hours， the train line to take this break 7 shares issued to the line can be carried out next train In the next train， the train originating from， to start again from the arrival terminal， at least 45 minutes 10 seconds (downlink direction) / 44 minutes 15 seconds (uplink direction)， only reached the next train (Tianjin Station) ， The peak hours up to be able to start 15; as early summit and to meet the needs of start， Tianjin night stand at least 10 more At departure time， since the peak hours then made 15 pairs of trains (because of the train station stop in the middle)， end-to-fat line of departure and arrival capacity is tight， so the train departure point in time there is no law that can not be established standardized plans to run
In this paper， railway bedproblems are classified， corresponding causes are analized， problem addressing approaches are presented， and conclude that it is fundamental to understand all types of railway bed problems and how it comes so that we can detect them accurately and do effective precaution and 可以的话把后面的发给你
