| Abstract: | Structural and deformation feature of metro tunnel is discussed in this paper. Then long distance fiber sensing technique, based on BOTDR, is proposed to metro tunnel health monitoring. Flexural deformation of steel pipe with concrete cover is used to model metro tunnel deformation to test the ability of strain detection. As a result, the long distance fiber sensing technique shows many advantages, such as full range, in time, interference-free, duration. |
