Laboratory Study on Dynamic Properties of Compacted Residual Soil in Malaysia

This paper examines the dynamic deformation properties of a selected residual soil sample in Malaysia through a series of laboratory tests. The laboratory tests conducted include cyclic triaxial tests on the compacted residual soil with a measurement of deformation responses at small strains, and shaking table tests on a small soil block whereby the acceleration responses at different levels were analysed. The results showed that the dynamic deformation properties of the soil, namely the variation of shear modulus over a shear stain were ranging between 10(-5) and 10(-2). The results showed that the laboratory apparatus used herein were capable of evaluating the deformation properties of residual soil, and the G values obtained were comparable to those published data.
