THE MODEL OF RANDOM MEDIUM AND WAVEFIELD ANALYSIS IN 2-D SPACE

摘要：

In the new heterogeneous constitutive model of random fractured rock,we use the local radius r and the local fracture density P to describe the length of the fractured medium and the fracture space density in each distributed fracture zone respectively.When simulating the elastic properties of rocks containing a random spatial distribution of fracture size,the macro-mechanical properties (the elastic wave speeds) of the fractured rocks can be connected with the model parameters (r and P).Numerical example indicates that it is possible for modeling a real heterogeneous medium effectively if appropriate model parameters are chosen.
