Abstract

In the process of deep roadway excavation, the rock mass is subjected to periodic load and high geostress, so the general strength criterion cannot describe the stress-strain curve of rock. However, the cyclic loading and unloading constitutive model of rock under high geostress is the key to predict the long-term stability of deep roadway under periodic load, thus it is urgent to carry out the study of rock constitutive model under high confining pressure. The process of rock subjected to external load to failure presents the propagation of original cracks, growth and propagation of new crack. Previous studies have shown that the number of cracks in rock obeys Weibull distribution and the Griffith criterion assumes that the failure of rock is caused by the crack propagation. Based on these criteria, this paper establishes a statistical damage constitutive theory of cyclic loading and unloading of rock under high confining pressure by extending Weibull statistical damage constitutive. Through the equation transformation of constitutive model, the threshold value of constitutive damage is studied. Furthermore, the constitutive parameters was fitted with the data of even cyclic loading and unloading test, and the evolution rule of the parameters is obtained. By comparing the constitutive theory with the odd cyclic loading and unloading test, the accuracy of the constitutive model is verified, which provides a new insight for the study of the constitutive model of rock under high confining pressure.
