以可靠性为中心的维修方法及其在隧道中的应用

Reliability-centered Maintenance Method and Its Application in a Tunnel

本文针对目前隧道监控维修状况及存在的问题,提出以可靠性为中心的维修(RCM)作为维修理念,并将其引入到隧道管理中,对隧道设备的故障模式及可靠性进行分析,并对RCM方法在隧道监控维修中的应用做了初步研究。最后通过案例说明,隧道采用RCM方法可有效降低维修费用,具有一定的经济效益和社会效益。

This study is presented in view of the current tunnel monitoring maintenance status and existing problems, and proposes reliability-centered maintenance （RCM） as a maintenance concept. RCM can be introduced into tunnel management. Accordingly, a preliminary study on the application of the RCM method in tunnel monitoring maintenance is performed through the tunnel equipment failure mode and a reliability analysis. Finally, by adopting a case, this study shows that a tunnel using the RCM analysis method can effectively reduce the maintenance cost, and has certain economic and social benefits.
