초록

The Prefabricated Vertical Drains (PVDs) method is one of the most widely used techniques to accelerate the consolidation process in-situ and hence increase its bearing capacity. In this paper, the degree of consolidation incorporated with PVDs was evaluated in O construction work site which composed with dredged soil. O Program PVD(Version 2.3) which developed by Asian Institute of Technology was used. The purpose of this analysis is efficiently to estimate the degree of consolidation by analyzing the surface settlement with time, and drainage at initial stage and final stage by using design-parameter which based on the in-situ tests and laboratory tests. This result can be compared with analysis of the degree of consolidation using Program PVD(Version 2.3) and the field observed data in the future studies.
