Abstract

Abstract

FBG and PPP-BOTDA are applied to anchor bolt pull-out test in the indoor together, and the test results are verified by ANSYS numerical simulation. The results indicate that the axial stress of bolt under different pull-out loads measured by FBG and BOTDA sensors shows a “negative exponential distribution”, and the influence range of load is mainly concentrated within 55 cm from the orifice, which is basically consistent with the results obtained by numerical simulation; FBG-BOTDA combined sensing technology can not only accurately obtain the stress condition of key points, but also comprehensively monitor the stress area and stress distribution of the bolt.
