STRENGTH AND DEFORMATION CHARACTERISTICS OF IMPROVED RUBBLE MOUND WITH PLASTIC GROUT FILLED VOID

Abstract

 Recently, demand for deepening of existing quay has been increasing. A new method by grouting was developed which enables deepening of existing gravity-type quay wall without realignment by consolidating part of rubble mound. It is necessary for actual execution to interpret appropriate strength properties determined by site conditions when setting or implementing a design strength of improved clods, and determination of the quality of improved clods as well. Then several strength tests were conducted and confirmed its adaptability. In addition durability against repeated load by tidal fluctuation and earthquake was verified.
