| Abstract: | The acoustic emission characteristics of sandstone under fracturing are studied by simulating the stress state of the tunnel enclosing rock using the real three axle press.The results show that the characteristics of acoustic emission of the tunnel enclosing rock varies before fracturing with their different fracturing modes and surface forms.The rational parameters for the stability monitoring and forecast of the tunnel enclosing rock are put forward. |
