PENAMBAHAN LAPISAN PASIR PADAT SEBAGAI SOLUSI MASALAH PENURUNAN FONDASI DI ATAS LAPISAN LEMPUNG LUNAK : SUATU STUDI MODEL
ABTRACT: Settlement and
bearing capacity is a problem
in the construction
of foundation on
soft clay layer.
The addition of a
dence sand layer
under the foundation
is able to
reduce magnitude of
the settlement and improve bearing capacity on soft soil.
This study aims to determine the effect of the thickness of the sand layer
under the foundation againt the type of soil shear failure an d load-settlement
curves. Static loading is done on the 6 x 6 cm 2 and 9 x 9 cm2 foundation
model. The thickness of the sand layer is 0, 1/6 B, 1/3 and ½ B. The results
showed the addition
of B ½
thick layer of sand under
the foundation increase
soil bearing capacity 221% for
the foundation model 6 x 6 cm2 and 120% for the foundation model 9 x 9 cm2.
General shear failure occurs in the thickness of the sand layer ½ the addition
of B.
