Abstract
This paper examines the validity of the Monte-Carlo simulation of fracture networks (MSFN) and the real-time inversion analysis (RTIA). The MSFN is applied to simulate the consolidation grouting and curtain grouting. Fairly good agreement with observed data is obtained for the relation between the pressure and amount of grout agents, 2) the spacial variation of Legion values, and 3) the appearance of grout agents in adjacent holes. The basic validity of the RTIA is verified through simple examples. Then, it is shown that the RTIA can predict the water channel conditions and the grouting distance for the consolidation grouting.
