Land Reclamation and Settlement of Reclaimed Land for New Ports
Publication: Ports 2019: Port Engineering
ABSTRACT
Materials dredged from seabed and construction waste soils have been used for land reclamation for the development of sea ports in Singapore. Ground improvement employing surcharge and flexible drains are employed to accelerate the ground settlement. This article first examines the characterization of the inhomogeneous fill ground before ground improvement. It then evaluates the gain in soil strength and observed settlement of the reclaimed land after ground improvement. By comparing the soil properties before and after ground improvement, it is established that soil strength measurement is the most reliable mean to evaluate the effectiveness of the adopted ground improvement scheme. Other soil test data such as pre-consolidation pressure and moisture content do not provide convincing evidence. For the observed ground settlement during ground improvement, it is found necessary to interpret the settlement data with proper consideration including height of surcharge at various locations and the presence of surcharge and construction activities nearby.

ACKNOWLEDGEMENTS
For the case study of the very large land reclamation project presented in this article, many engineers from the agencies, consultants and contractors are involved. The authors wish to express their sincere gratitude for the many useful and insightful inputs provided by the above mentioned engineers. In particular, they wish to thank the significant efforts of Dr Kee Kiat Tho in performing the tedious three-dimensional finite element analysis. The authors wish to state that the findings presented in this article are entirely the interpretations of their own and not necessary represent the opinions of the agencies, consultants and contractors.
