Abstract
The performance degradation of secondary lining is the main disease that affects the tunnel operation. Therefore,safety analysis on the secondary lining structure by optical fiber communication technology means importance to the tunnel operates health.According to the actual monitoring data,which is monitored by the optical fiber Bragg grating strain sensor embedded on the secondary lining of Tianxin tunnel,the best typical function model are selected for the non-linear regression analysis and then the regression curves which reflect the strain development variation trend are obtained.Results indicate that test methods achieved the judgment of tunnel structure stability by forecasting support nursing structure(monitoring points)strain trend,judging support nursing effect and analyzing on current and eventually tunnel stability of supporting structure.

期刊介绍：
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
