摘　　要：针对当前铁路营业线桥涵施工导致的列车晃车以及铁路交通事故频繁发生现象,基于WSN技术的特点和应用前景,结合铁路营业线桥涵施工的特点和施工过程遇到的问题,采用传感器技术建立了基于WSN技术的施工监测防护体系.研究结果表明:以加速度监测为例,分析影响营业线桥涵施工中轨道所受加速度大小的因素,并选用无线加速度传感器建立监测系统,对列车经过时桥涵施工中便梁受到的加速度值进行实时监测、分析和处理,验证列车行车安全,能够有力地保证施工顺利进行.WSN技术具有高精度、低成本的特点,能够为营业线桥涵施工和列车运营提供安全保障.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.
