Pengaruh Beban Kendaraan sebagai Beban Titik terhadap Deformasi Geogrid sebagai Perkuatan Embankment di atas Tanah Lunak
Abstract: Public contructions
built on soft soil such as clay would face some problems such as long period
consolidation time, unstability 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 and floating piles were modelled in plane strain too. Point load on top
of embanknet were variated, they were 20, 40 and 60 kN/m. The simulation was
carried out in staged contruction mode. The implementation of vehicle load
increased geogrid deformation. It appeared as geogrid vertical displacement
when the biggest vehicle load ( 60 kn/m) applied. In long term loading
condition where excess pore water pressure was very small, vertical
displacement of geogrid was – 0,5062 m for rigid embankment and – 0,6568 m for
interface embankment. The difference occured due to slip at the interface of
geogrid and soil. It leaded to adding soil mass supported by geogrid,
furthermore the deflection of geogrid became bigger.
