According to the experimental force of optical fiber in an earth dam model, an analysis model of fiber embeded in an earth dam is set up using ansys 9.0 software. Stress analysis of optical fiber in dams becomes easy after the boundary conditions is simplified. The deformation of optical fiber under different pressure loads are calculated. The relationship between the stress and the weight applied to the optical fiber is obtained while the settlement occurred in the dam model, even badly collaps happened. The relationship between the depth of the optical fiber away the top of the dam model and the sensitivity of optical fiber to applied loads is described.
