%X Grouting is a strengthening method which uses cement or other materials to fill up the fractures and voids in rock masses. As a result, the stability is improved and the permeability is reduced. But for the practical engineering, the grouting effect can be varied from very strong to very limited. As the effectiveness of grouting depends very much on the understanding of grouting process, it is important to research the process considering fractures and its connected structure in rock masses and also the non-Newtonian nature of the grouting. The final grouting reinforcement effect also depends on the enhanced strength or deformability of the fractures or grouted rock masses. Based on the grouting theories, testing researches and monitoring of grouting effect, some important points needed to research are pointed out, and the developing direction of grouting technology researches in future is also demonstrated.
