Pengaruh Beban Kendaraan sebagai Beban Terbagi Rata terhadap Deformasi Geogrid sebagai Perkuatan Embankment
Abstract: Soft soil such as
clay was sensitive soil. Public contructions built in this kind of soil would
face some problemssuch as long period consolidation time, unstable embankment
slope, not easily compacted and high level settlement. Some solution that could
be suggested were the usage of vertical drain, or the usage of geosynthetics
material such as geogrid combined with floating
piles.Analysis was carried out by using plaxis version 7.2. soil for
embankment and embankment foundation was modelled in plane strain. Also geogrid
andfloating piles were modelled in palne strain too. Surcharge load on top of
embanknet were variated, they were 20, 35 and 50 kPa. The simulation was
carried out in staged contruction mode.Final vertical displacement in geogrid
due to 50 kPa vehicle load as surcharge
load and long term load period (in this case excess pore water pressure was
small) was -0,9062 m for rigid
embankment and -1,4206 for interface embankment. The difference occured due to
slip at the interface of geogrid and soil. It
leaded to adding soil mass supportd by geogrid, furthermore the
deflection of geogrid became bigger.
