Abstract:By using the basic principle of continuous damage mechanics as a reference, together with the statistical strength theory based on the Weibull distribution, a new constitutive model of fractured rock masses for deep underground engineering is proposed. In this model, a new definition of the fracture degree Ft has been proposed for the first time, which can quantitatively describe the fracturing process of a fractured rock mass. Based on the results of laboratory tests and numerical simulations for fractured ro… Show more
