Various kinds of measurements were carried out during excavation of two large underground caverns to estimate rock behavior as a discontinuous material. As a result, rock behavior as a discontinuous material was estimated in detail, such as characteristics of crack propagation, displacement and stress redistribution. In particular, it was found that characteristics of displacement and stress redistribution were very remarkable in some areas and that crack propagation was also remarkable in the area. Through the measurements, it was suggested that the sliding of discontinuities were related to the discontinuous behavior. So with a simulation in which the discontinuities were modeled, the influence of the sliding of the discontinuity to crack propagation, displacement and stress redistribution is discussed.
