摘　　要：隧道内接触网预埋槽道通过直接浇筑与隧道混凝土融为一体,运营期间无法准确获知预埋槽道在隧道混凝土内的服役状况。本文提出一种接触网预埋槽道服役状态监测装置及监测方法,在不破坏隧道二衬结构的情况下,利用倒T型锚杆和预埋槽道本体获取观测地段有效数据,解决了现有预埋槽道安装后无法获知锈蚀情况的问题。The OCS pre-embedded channels inside the tunnel are integrated with the tunnel as one through direct pouring.It is impossible to acknowledge the service state of pre-embedded channels inside the concrete of the tunnel.The paper puts forward a monitoring device and monitoring method for service state of OCS pre-embedded channels,which is able to obtain the effective data of the investigated section by means of T type anchor bolt and main body of the pre-embedded channel,solving the problem that the status of corrosion of pre-embedded channel is impossible to be acknowledged after its installation.
