APPLICATION OF VACUUM CONSOLIDATION METHOD FOR CLAY GROUND AND GROUND BEHAVIOR UNDER CONSTRUCTION OF EXTRA-EMBANKMENT

Abstract

 To construct an extra-embankment for the disposal pond of dredged clays, the vacuum consolidation method for the reclaimed clay ground was performed. In this paper, the design and construction of vacuum consolidation method for the reclaimed clay ground were outlined. From the results of back-analysis using data of the monitoring and ground survey, the design of vacuum consolidation method for such ground was assessed. It was pointed out that the determination method of model ground for such soft reclaimed clay ground was important. And the determination method using reclamation analysis was proposed. The ground behavior under the construction of extra-embankment was also shown.
