摘要

In order to minimize losses due to landslides, slope displacement monitoring is a vital early warning system. As a result, the internal deformation of the slope was monitored using distributed fiber optic sensing technology based on Brillouin optical time domain reflectometer (BOTDR) attached on the casing of the in-place inclinometer (IPI). Primarily, laboratory experiment was conducted followed by large scale physical slope model. The strain changes in the large-scale model were measured at regular interval of 10 minutes respectively. The finding demonstrated that the calculated displacements measured by both of the devices were closed to each other as well as a consistency was observed between them. Moreover, it was also found that the offer mentioned application can accurately locate the location of potential sliding surface and provide adequate access to the internal deformation of the slope.
