Abstract

Grouting is widely used to improve in-situ soil/rock quality and, in this regard, various injection techniques have been developed. From a rock engineering point of view, penetration grouting (also called permeation grouting) is commonly used to fill the voids of the jointed rock mass so as to improve the rock stiffness and strength and reduce groundwater flow potentials.The nature of grouting in rock is different from that of soil. Within a jointed rock mass, the intersection of pre-existing discontinuities forms a network of fractures that provide the grout penetration path.Therefore, the geometric properties of discontinuities play a significant role in the grouting process. Moreover, the grout penetration radius into the rock mass is a function of discontinuity geometry, grout characteristics and grouting pressure. It is the intention of this paper to conduct a parametric analysis of the role of the above parameters on the grouting process. The Distict Element Method (DEM) was employed to carry out a comprehensive numerical analysis of the role of the important parameters mentioned above on the grouting process. The roles of all parameters were compared against one another and summarized in a diagram. The obtained results agree well with field observations, but, it is believed that further work is required, in order to be able to incorporate the numerical findings to actual field conditions.
