Abstract
Provided is a device for predicting an underground behavior by using an acoustic emission (AE) sensor, including: a waveguide rod having an elongated end to be inserted in a borehole; a plurality of acoustic emission sensors mounted on different positions of the waveguide rod; a wrapping layer configured to cover a circumferential surface of the waveguide rod such that a gap is formed between the waveguide rod and the wrapping layer; an acoustic emission generating layer filled into the gap and being homogeneous along a direction of the waveguide rod; and a grouting layer configured to fix the waveguide rod in the borehole.
