Description

Unsaturated drained triaxial tests were carried out previously to elucidate deformation behavior, the effective stress path, and water retention properties of Loam, volcanic soil, during shearing processes. We clarified the relation between the void ratio and van Genuchten parameters using water retention curves under drained and undrained triaxial tests conditions. Furthermore, we predicted the unsaturated shearing behavior by considering the void ratio dependence of water retention curves under drained conditions by applying the Nova model and Modified Cam-Clay model. Comparing results obtained with the Nova model with those of the Cam-Clay model, the former showed a slightly larger value. For axial strain of less than 5-10%, Nova model agreed well with laboratory test results.
