Abstract | Eight methods of soft soil improvement techniques are
applied to a trial embankment at the Muar flat in Malaysia
to evaluate their cost and effectiveness. These improvement
techniques can be classified into three groups, namely,
Mechanical Method CP reloading and Vertical Drains);
Structural Method (Concrete Pile and Compaction Sand Pile)
and Physical and Chemical Method C Electro- osmosis and
Sulphonated Petroleum Chemical Injection).
A preliminary study of these techniques
secondary soil data obtained from the trail
location is mad e. The studies include a review of
involved, construction methods and the relative
construction.

The soft clay deposit is very homogeneous and is about
20 m thick. The moisture content is high and exceeds liquid
limit. The organic content is less than 0. 5% and pH value
is between 5. 4 to 7. 7. Sensitivity range from 2 to 7. A 2m
thick weathered crust is found on the surface. The field
vane shear strength varies from 10 kN/ml below the crust to
40 kN/ml at 1 Bm depth. su/crv0 ' =O. 31, and ch = 2cv.
It is found that earth fill preloading and vertical
drains are likely to be effective and cheap. However, the
difficulties and uncertainties in determination and
selection of design parameters make an accurate prediction
of rate of settlement difficult.
The effectiveness of piled embankment has been proved
by successful construction cases in the region. The cost of
construction is high when the soft clay deposit is thick.
Suitability of other less commonly used physical and
chemical methods are also discussed. |
