ABSTRACT: The design and construction of embankment over very soft compressible alluvial deposits has
always been a challenging task for Engineers. This paper presents a set of guidelines for the design and
selection of construction methods for embankment taking into considerations of safety, direct and indirect
costs, duration of completion and other cost benefits. Various commonly used ground treatment techniques
are also briefly discussed.
The construction of embankment (including
reclamation with hydraulic fills) over very soft
compressible alluvial deposits (e.g. Clay, silty Clay,
clayey Silt etc.) is increasing due to lack of suitable
land for infrastructures and other developments.
The choice of construction method in this formation
is not only governed by direct costs, but also the
long term maintenance costs, duration of
completion and cost benefits.
This paper presents brief guidelines for the
selection and design of the various commonly used
techniques for construction of embankment on soft
soils. General reviews of each of the methods are
made including a discussion on their use,
applicability and appropriateness. The
requirements for additional subsoil information or
instrumentation during construction will also be
