Abstract

<p>As a measure to increase the acceptance capacity of disposal pond for dredged clay in operation, the accelerated consolidation method, in which PVD is installed vertically, was adopted in Shinmoji-oki disposal pond. In this study, the issues of setting up the geotechnical model at the time of PVD installation and the effective period of PVD itself were focused. The validity of the method using the reclamation analysis with monitoring results proposed as a method to solve these problems and the effective period of the PVD itself were examined.</p>
