Abstract

The chemical grouting is one type of ground-improvement methods. It injects liquid
consolidation material into the gaps of a soft sandy ground. It is mainly used for improving a stable ground,
such as by preventing liquefaction and increasing the strength of the ground. Chemical grouting has been
successfully applied at many construction sites; however, the behavior of the chemical solution being
injected into the ground is unclear. Furthermore, because the ground involves uncertainty, it is difficult to
determine the penetration range of the chemicals (grouting materials). In this study, the authors carry out a
seepage flow analysis of a chemical solution for a ground requiring improvement due to uncertainty. They
then compare the difference in the behavior of the chemical solution between the case in which the ground is
assumed to be heterogeneous and that in which it is assumed to be homogeneous.
