The purpose of this paper is to determine the activities of rock deformation and failure around a tunnel, and to guaed the safety of a high building over the tunnel. The activities of building and rock around the tunnel were measured by using the EAE-04 acoustic and electromagnetic system. The effective AE (acoustic emission) EME (electromagnetic emission) signals are determined, and the noises eliminated by referring to the relationship between the risetime and duration of the signal. The rock… Expand
