Abstract

Rock mass may have different properties in different regions of its structure. An example is a shaft where three different regions (concrete lining, Excavation Disturbed Zone (EDZ), and in situ rock mass) must be considered.

For application in this case, FRACOD needs to simulate the multiple regions with different material properties. Because FRACOD is a boundary element code based on the mathematical solutions in an elastic, homogeneous, isotropic medium, it is not a trivial task to extend FRACOD to handle multiple region problems. New approaches must be found. This chapter presents the mathematical formulations and their implementation in FRACOD for multiple region problems.
