HU Zhongchun1,2,ZHAO Likun2,3,LIU Yongcheng1,REN Gaofeng2(1.China Railway 14 Group Corporation,Jinan 250014,China;2.School of Resource and Environment Engineering,Wuhan University of Technology,Wuhan 430070,China; 3.PLA 96501 Unit,Luoyang 471023,China)  
Considering the phenomenon of train shaking and frequent railway traffic accidents caused by the construction of bridges and culverts on operating railway lines,this dissertation established the monitoring and protection systembased on the characteristics and the promising applications of WSN technology and combined with the problems and features of bridge and culvert construction on the operating lines.The study shows that,taking monitoring the acceleration as an example,choosing wireless acceleration sensor and establishing monitoring system for analyzing the effect of acceleration values while trains are passing,keeping analyzing and disposing the monitoring data to test and verify the safety of train operation can effectively ensure the smooth construction.WSN is precise and low-cost;it can provide safe construction of bridges and culverts and railway transportation.
