ABSTRACT:
Numerical methods can provide extremely
powerful tools for analysis and design of engineering systems with complex
factors that are not possible or very difficult with the use of the conventional
methods. In this paper, we use the 2-D boundary element method (BEM) program to
model elastic wave excited by a point explosive source propagating in cracked
rocks. As an example, we consider the typical crack distributions in rocks,
both models for the real crack structure are also talked about. The elastic
wave propagating in rocks with aligned cracks and parallel fractures is
assumed. Effects of different crack parameters, such as crack scale length and crack
density are analyzed. Numerical results show that the BEM is a powerful
interpretive tool for understanding the complicated wave propagation and
interaction in cracked solids.
