چکیده انگلیسی
This paper proposes an effective and convenient method to analyze slope stability in real time, which is based on fiber Bragg grating (FBG) sensors. First, a new type of FBG inclinometer is designed to capture the internal slope displacement variation considering temperature compensation, and an optimum displacement algorithm is selected by an experiment. Once the monitoring work is prepared, the potential slope slip surface is determined by monitored displacement in an optimization model based on the maximum displacement increment of the objective function. Finally, integral processing is used with the Bishop method to simplify the calculation, and a safety factor is estimated by the integral method. An experimental model test of homogeneous soil is conducted to verify the feasibility and reliability of the proposed analytical method and the FBG monitoring technique.
