CPTU Penetrations into the Marine Clays and Laterite Soils of Northwest Peninsular Malaysia
Abstract Site investigation penetrations by CPTU were carried out in Northwest Peninsular Malaysia to demonstrate the contrasting profiles between the marine clays of the coastal plains and the laterite soils of the inlands. From the findings, the trends of persistent low resistance with depth for the marine clays and fluctuating higher resistance with depth for the laterite soils were found quite consistent when evaluated in terms of either the cone resistance, sleeve friction, or standard penetration number. The CPTU interpreted behaviors for the various marine clays were clayey silt to silty clay, clay, sensitive fine grain, and silty clay to clay, to mention the most dominant ones, while for the underlying hard layer were sand and sand to silty sand. The CPTU interpreted behaviors for the laterite soils, among others, were silty clay to clay, clay, clayey silt to silty clay, silty sand to sandy silt, and sand to silty sand. In addition, the laboratory classification procedure, namely the Unified Soil Classification System, gave a different name for each of the CPTU interpreted behaviors, for the marine clays and for the laterite soils, which this paper shows and clarifies. The CPTU penetrations reaffirmed that the marine clays of the quaternary coastal plains are clayey and very soft while the laterite residual soils of the inlands are relatively more sandy and stronger.
