Abstract: In geotechnical engineering, fracture fillings or rough fracture surfaces often resist deformation and enhance the equivalent elastic moduli of fractured rock masses. In this study, the normal stiffness and shear stiffness ...

Abstract: For tunneling in squeezing rock, large deformation induced by tunnel excavation and creep of squeezing rock has been a great challenge during construction. This large deformation would keep growing for a long time, ...
