Abstract: | For Harbin-Dalian Railway passenger dedicated line which is the first operational passenger dedicated line in severe cold and high latitude regions in China,many key technologies were creatively used in the design of bridge engineering. In here,it was the first time in China that a special bridge type was achieved,which consists of steel-box superimposed arch and solid round-steel suspenders; it was the first time in China that the high-speed railway turnout No. 42 for continuous welded rail was installed upon a small-span reinforced concrete continuous girder; there was the longest one of all the multi-span units used in continuous girder bridges on passenger dedicated lines in severe cold regions; it was the first timein China that a long-span continuous girder on passenger dedicated line was erected by swing method after being concreted in the form of long segments upon the support frames. In addition,combined with natural environment of Shenyang-Harbin section in severe cold and high latitude region,some technical measures were employed in the design of bridge engineering and were introduced here. |
