Assessment of Field Applicability for Suction Drain Method

摘要

In this study, field test was performed at the OO reclaimed site in Gyeonggi-Do to identify field applicability of suction drain method based on determined effect factors from laboratory tests. A target site which has thickness of 10m was divided in two sections, and two kinds of drains selected from laboratory test were installed in each section. To prevent a loss of vacuum pressure, the upper 1m layer of target site was left as a sealing layer. Step vacuum pressure was applied to prevent formation of a 'Hardening Zone', and finally 80 kPa of vacuum pressure were applied.
