Deformasi Vertikal Dan Horisontal Pada Tanah Lunak Di Bawah Trial Embankment Di Kendal, Kaliwungu, Semarang
Abstract: Soft soil as
foundation soil always became problems related to constructions those were
constructed on it. The understanding of physical and mechanical properties of
soft soil were important for understanding the behaviour of this soil due to
vertical loading. One of types of vertical loading was trial embankment. The
analysis for vertical and horizontal deformation in soft soil carried out by
comparing between the data resulted from field measurement and from numerical
simulation. Numerical simulation carried out by using Plaxis version 7.0. In
this simulation, soft soil and embankment soil were modelled in Mohr-Coulomb
model material. The results of the analysis showed that there was an
increasement in soft soil shear strength. This condition led to the decreasement
in horizontal deformation. The extreme difference in horizontal deformation
between field measurement and numerical simulaton caused by the difference
assumption used in soil modeling. For instance modulus of elasticity
assumption, soil homogeneity assumption, and fixed condition at the bottom edge
of inclinometer. Maximum vertical deformation in soft soil occurred under the
center of trial embankment. It happened because the highest compression
occurred in this area when the maximum height of embankment reached. This
condition led to highest burden supported by the soil under the center of trial
embankment.
