A Rock Mass Classification Method for Tuff Tunnel Based on the High-Pressure Gas Expansion Method
A precise rock mass grade result is crucial for directing the tunnel excavation engineering design. A novel rock mass classification method for tuff tunnel based on the high-pressure gas expansion method (HPGEM) was proposed, which was primarily built on

Study on Interfacial Crack Initiation of Jointed Rock Mass Based on Interface Fracture Mechanics
The fracture of interfacial crack is the main failure type of jointed rock mass. Therefore, it is very important to study the interfacial fracture of jointed rock mass. For the similarity of jointed rock mass and composites (all are composed by two parts,
