SOIL FOUNDATION IMPROVEMENT WITH TIRE-USED TO REDUCE SETTLEMENT OF SHALLOW FOUNDATION EMBEDDED ON SATURATED DEPOK CLAY
ABSTRACT: One of
soil foundation improvement
methods to anticipate
the problem of
settlement is to
use tire-used (pneusol). This
is a preliminary
study and aims
to determine the
reduction of vertical
displacement or settlement on
saturated clay reinforced
with tire-used. Tire-used
material generally has
a density of between 8 and 10 kn/m3 and is usually
classified as a material lightweight tire. Laboratory model test used 4 (four)
models, model with and without tire-used and some variations of foundation
model size (rollag). Ratio of the diameter of tire-used and rollag size is
0.60. Results are compared with the data obtained by plaxis program.
Analysis of the
plaxis program assumed that
plane strain triangle
element type; 6
(six) nodes element; mohr
– coulomb criteria;
and soil foundation
in undrained condition.
Results of the experimental model
at laboratory works
show that the
tire-used can reduce
the settlement of
soil foundation up to
20% at maximum
normal stress. However,
the value of
settlement obtained by experimental model at laboratory works
could not be compared with the plaxis program results.
