Analisis Perubahan Tekanan Air Pori pada Tanah Lunak akibat Beban Trial Embankmentdengan menggunakan Plaxis Versi 7.2.
Abstract: Soft soil could be
found easily in Indonesia. Constructions that built on this soil; such as
embankment; face some obstructions, for instance long period consolidation,
difficult soil compaction, unstable slope of embankment and high settlement
value for long period. Consolidation related to particle size of soil grains,
soil permeability coefficient and pore size between soil particles. This
research was carried out with numerical simulation and aimed to analyze the
change in pore water pressures in soft soil due to embankment load.
Numerical simulation was carried out by using Plaxis version 7.2. The
time periods for construction and consolidation were the same with field
measurement values. Total times for both stages were 102 days. Material model
used were Mohr Coulomb Model and input material model that were used were the
same with filed measurement values.
The results showed that at the end of construction stage there always an
increasement in pore water pressure (excess pore water pressure existed) and
the decreasement of pore water pressure occurred in consolidation period.
Excess pore water pressures of soil below embankment were at area A, depth 0,5
was -22,8093 kPa, at area B (depth 9 m) was -21,5576 kPa and at area C (depth
13 m) was -14,159 kPa.
