Abstract

The mechanical properties of rock mainly refer to the deformation characteristics and strength of rock. The strength and deformation characteristics of rock are closely related to rock engineering. Therefore, it is necessary to clearly understand the mechanical properties of rocks and their reflection under physical environment and stress conditions. This chapter first introduces the mechanical properties of rock under room temperature and pressure, and then introduces the influence law of confining pressure, intermediate principal stress, temperature, pore pressure and strain rate on the triaxial mechanical properties of rock.
