Abstract

Reclaimed sites in Singapore are usually underlain by highly compressible marine clay. The evaluation of the state of consolidation of the underlying clay is important for the development of recently reclaimed sites. Three in-situ tests, the piezocone penetration test (CPTU), the flat dilatometer test (DMT) and the field vane test (FVT) were used for evaluating the vertical yield stress of the foundation clay underlying a large reclaimed site in Singapore using interpretation methods developed on the basis of Cam clay model. Interpreted values of overconsolidation ratio (OCR) from the CPTU and the FVT were slightly higher or comparable to those deduced directly from oedometer tests and in-situ porewater pressure measurements using field piezometers and the piezocone. The OCR values interpreted from the DMT were generally lower than those directly measured. Th in-situ tests were found useful for evaluating the state of consolidation of clay
