Effect of micro-defects and macro-joints on stress wave propagation in rock mass

摘要

A rock mass is a material with various discontinuities different from other traditional structural materials in civil engineering. Ideally, a rock mass is composed of a system of rock blocks separated by discontinuities forming a material in which all elements behave in mutual dependence as a unit. Therefore, the dynamic properties of rock mass are characterized by mechanical and geometrical properties of discontinuities. Investigating the mechanical effect of rock blocks and discontinuities on the stress wave propagation is important in solving problems of seismology, mining, tunneling, underground constructions, etc.
