Abstract

Construction over soft soils in this country is something that cannot be avoided due to the lack of available good bearing soil for construction. The modern techniques of reinforcing soft soils consist of continuous inclusions of synthetic strips, fabrics, and grids into an earth mass. The used of natural fibre such as oil palm fibre which is abundant in this country probably has the potential to be used as a cheaper version of soft soils reinforcement material. In this study, random inclusion of oil palm fibre (OPF) is investigated as a soil reinforcement method. Four different percentages of OPF, 0.25%, 0.5%, 0.75% and 1% by weight of raw soft soil are considered. The investigation covers the effect of OPF in soil on compaction and shear strength behaviour. The reinforced soil samples were subjected to compaction and triaxial compression tests. The results of these tests shown a significant improvement in the failure deviator stress and shear strength parameters (C and Φ) of the studied soil. It is observed that the fibres act to interlock particles and group of particles in a unitary coherent matrix thus increasing the strength properties of the soil.
