The discussant of this paper points out that the technique described by the authors is developed empirically with little theoretical guidance. A simple theory is proposed that is based on a model that agrees with Graf's observation of compaction grouting, which to a first-order approximation predicts the correct grouting pressures for the process. The conditions are described for a spherical grout mass, and the derivation of equations are detailed. Design curves are presented which offer a convenient means of predicting the order of magnitude of the maximum allowabe grouting pressure in actual compaction grouting since the phi and h (distance of the center) values are normally available. The diameter of the grouted mass can be estimated by measuring the volume of grout that has been pumped in.
