It is very important to study stress wave propagation crossing jointed rock masses for the exploiting safety of energy and mineral resources.Combined with characteristic method,time-domain recursion method and equivalent medium method and virtual wave source method,considering the joint constitutive relation and boundary condition,the recursion equations on speed wave and stress wave are presented,and then numerical resolutions on transmission and reflection coefficients of stress wave resulting form joint parameters are derived.On the base,hot points in the future in the field of stress wave propagation through the joint are discussed.Some advices on future research are given.
