Abstract: Studying stress wave propagation across jointed rock masses is essential for the stability of rock engineering.Rock masses in nature include many joints,which have great influence on stress wave propagation.During wave propagation across rock masses,both of the amplitude and speed of the wave attenuate.Meanwhile,the interaction between the stress wave and the joints usually results the joints open,close and slippery.Currently,some analytical methods have been successfully applied-for studying one-dimensional or two-dimensional wave propagation across rock joints.These analytical methods are divided into three types:the discontinuous medium method,the equivalent continuous medium methods and double-scale discontinuous method.Based on these two methods,the effect of linear and nonlinear joints on wave propagation has been studied effectively.The present paper is to introduce the discontinuous and equivalent continuous media methods,discuss their applicability,and suggest the further problems to study.
