Integrated soil investigation works off marina east, Singapore

摘要

As part of preliminary site investigation for the Marina East area, an extensive soil investigationrnworks were planned. The project site is located in waters off Marina East, Singapore. . The whole project siterncovered an area of around 600 Hectare. The water depth at the project area varies from 0 m CD to -23 m CD.rnThe seabed within the project site is mainly covered by Kallang Formation and Old Alluvium. The seabed geology,rnin particular, the thickness and distribution of the soft sediment and soft clay within this project site, asrnwell as the strength and stiffness characteristic of these soft deposit are the main concerns for any new developmentrnover this site. The knowledge of seabed geology and the engineering properties will help in decidingrnthe appropriate facilities to be built or/and the appropriate method of construction. In view of the nature of therndesign requirements, an integrated soil investigation works has been designed. This includes 4 key components:rnseismic survey, CPT, borehole, and Large Diameter Borehole. Proper planning and management wasrnsignificant for such a mega soil investigation project, which covers a huge project area and includes a few differentrntypes of work.
