The Compression Behaviour of Intact Marine Clay in Malaysia

Recent development in economic and the search of new energy has brought to the usage of
area with plenty of marine clay. This soil creates several complexities in geotechnical design
due to high compression behaviour and low bearing capacity. 8 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 0.564 – 0.611 as the percentage finer increased, thus the compressibility of
soil is mainly controlled by the fines particles. The preconsolidation pressure for all samples
ranged from 200 – 500 kPa which can be compared with the presence literature for the
compression behaviour towards denser soil. In conclusion, the compression behaviour of
intact soil is close related with the basic soil properties and structure effect of soil.
