| 摘 要： | The paper gives a brief introduction to the design concept of ＂bridge instead of embankment＂ for Qinghai-Tibet Railway, and illustrates an optimised structure style and corresponding considerations for the bridges built in unsteady frozen ground zone in Qinghai-Tibet Plateau. The dynamic simulation analysis of trairrbridge system fro verifying its safety level and Spedin ride index during operation and Excel VBA programming technology for improving design efficiency are also mentioned in this paper.
