EVALUATION OF THE SETTLEMENT OF IN-SITU IMPROVED GROUND USING SHALLOW STABILIZATION AND FLOATING-TYPE CEMENT-TREATED COLUMNS

Abstract

  The use of shallow stabilization and floating-type cement-treated columns has been developed as a method with accepetable settlement for maintaining the proper functioning of high standard roads or high embankement on soft ground. So it is most important to predict total settlement for this type of improved ground. In this study, consolidation properties of this type improved ground were clarified by the field observation results obtained from two kind of full scale test embankments. Further, a method for predicting the total settlement for this type improved ground with respect to the improvement parameters is proposed. Its validity is confirmed from field observation results.
