Research on the Evolution of Shield Segment Cracks Based on Acoustic Emission and CMOD

Research on the Evolution of Shield Segment Cracks Based on Acoustic Emission and CMOD

In order to explore the cracking law and failure characteristics of segments, a model test of shield segment cracking was conducted. The microscopic and macroscopic crack evolution process of the segment is studied by using acoustic emission detection technology and crack opening displacement (CMOD)...
