Analisis Deformasi Vertikal Dan Horisontal Tanah Lunak Di Bawah piled-Geogrid Supported Embankment
Abstract: Soft soil was easily
founded in Indonesia. it was a low permeability soil. Constructing building
such as embankment, roads on this kind of soil often faced problems. They were
long term settlement, long term construction time and consolidation. Some
method could be good alternative to overcome these problems such the usage of
vertical drains, soil reinforcement, orsoil stabilization. This research
carried out numerical simulation on piled-geogrid supported embankment. The
simulation used Plaxis version 7.2 software to calculate some iterations. Used
in this software as soil parameter input was Mohr-Coulomb Soil Model. Plane strain
model was used for floating piles and geogrid. The results showed that the
usage of floating piles and geogrid could reduce soil deformation. The
reduction in horizontal deformation during contructing embankment were 60 to 68
% for rigid embankment and 80 to 60 % for interface embankment. Meanwhile the
reduction in vertical deformation during contructing embankment were 60 to 65 %
for rigid embankment and 80 to 65 % for interface embankment..
