The Mechanical Behaviour of Reconstituted Marine Clay in Semantan Field

Throughout the years, the positive growth in Malaysia economy has increased the usage of new
technology in area consists of marine clay. The condition of the soil which very soft creates
complexities in design due to low bearing capacity and high compression behaviour.5 oedometer
tests were performed in this project to study the compression curves under one-dimensional
loading from shallow to deeper depth of soil sample taken. Result shows that the compression
index increased from 0.341 – 0.409 for reconstituted samples as the percentage finer increased,
thus the compressibility of soil is mainly controlled by the fines particles. The preconsolidation
pressure for two reconstituted samples are 3 kPa. In conclusion, the compression behaviour of
reconstituted soil is close related with the basic soil properties and non-structure effect of soil.
