Synopsis
The Compaction grouting (CPG) method is one of the liquefaction countermeasures to increase
the density of improved ground by injecting mortar statically into the ground. CPG is often adopted
just below or near the existing structures, and accordingly ground upheaval often becomes aproblem. In this study, a series of model and field experiments were conducted for the purpose ofdeveloping a new method which has more efficiency than the conventional construction’s upheaval
control. The proposed method has proven itself in reducing the ground upheaval quantity by morethan 80 %. Furthermore, the results demonstrate that the ground density, K-value and effect ofliquefaction countermeasures can be significantly increased by the new Up and Down method (U/D
method). Moreover, by using the concept of an equivalent improvement rate, it is possible to predictthe upheaval amount and density increase of the improved ground by the new U/D method, thereby
facilitating a rational design based on the conventional CPG method. The construction efficiency
and upheaval control mechanism of the new method was also examined. It was found that theworkability can be improved by using an injection pipe with a tip end tapered shape. The upheaval
control mechanism can be explained by the cyclic contraction of the ground due to the up and downof the new CPG method.
