The results show that the cumulative ringing count and cumulative energy curves of acoustic emission can be used to distinguish among crack closure, stable crack propagation, and unstable crack propagation. According to the change process of acoustic...

... is the preferred preselection area for HLW disposal in China. This area presents a typical Gobi landform, which has the following characteristics: flat terrain, bare bedrock and sparse vegetation. China's first URL is located in the Beishan Xinchang site. So far, five boreholes have been drilled in the site...
