Abstract: Soft soils such as marine clay and peaty soil can be easily found in this region. These soft foundation soils are compressible and therefore result in large consolidation settlement. As a result, soil subsidence is a major problem for road or rail road embankment constructed over soft foundation soil. This may lead to embankment failure, or sometimes restricting the height of the embankment, or limiting the rate of construction. The use of geosynthetic reinforced piled embankment (GRPE) system has gained popularity recently to overcome the problems arising from the construction of embankment over soft foundation soil. The objective of this research is to focus on the clarification of the key mechanisms and the development of suitable design methodology in designing a cost-effective GRPE system. This research encompasses two main goals: (1) to study some possible mechanisms of GRPE system, and (2) to translate this knowledge to useful design charts to select appropriate geosynthetic.
