Numerical analysis of embankment on soft soils with different / Rohamezan Rohim

The problem related to the soft soils deposits is an important role in geotechnical works. Soft soil is
very porous and fully saturated in nature. The degree of compressibility is high and low in undrained
shear strength due to high amount of moisture content. With the existing equipment, engineers sometime
forget or neglect the effect caused by the soft soils. The main problem faced by the structure
built on the soft soil such as embankment, excavation and tunnel is the effect of time dependent
deformation (during primary and secondary consolidation). Soft Soil Creep Model (SSC) and Soft
Soil Model (SS) are standard models that are available in PLAXIS. Another two new models are
Multilaminate Creep Model (MLC) and Multilaminate Soft Soil Model (MSS). These models were
developed recently in the Institute of Geotechnical Engineering, University of Stuttgart. Simulations
were conducted to investigate the horizontal and vertical displacements under specified loadings.
MSS model shows higher settlement and horizontal displacement after the construction of embankment
with 0.32m and 0.06m respectively. MLC model on the other hand shows the highest settlement
and horizontal displacement with 2.4m and 0.25m respectively.
