Opis

The majority of experimental studies on strainsoftening and instability behaviour of sand have beencarried out under axisymmetric conditions. However,most geotechnical structures such as slopes,embankments, and retaining walls, are notaxisymmetric problems and can only be simplified intoplane-strain conditions.A comprehensive experimental study on the strainsoftening and instability behaviour of a granularsoil under plane-strain conditions is presented inthis book. A new plane-strain apparatus was developedand used. The main features of the new plane-strainapparatus include appropriately enlarged andlubricated rigid platens using the free-end techniqueand four submersible load cells used for measurementof the lateral stress. In this study various specialisedplane-strain tests were carried out on very loose tomedium dense Changi sand retrieved from a reclamationsite in Singapore.The experiments presented in this book should helpshed some light on strain softening and instabilityphenomena of granular soils, and should be especiallyuseful to academics, researchers, and students, oranyone else who may be interested in experimentalsoil mechanics.
