ABSTRACT: Anisotropic behaviour of clay core, blanket, and foundation in earth fill dams may be a result of environmental loading such as wetting-drying and freeze-thaw cycles. The depositional process of the foundation soil and the compaction of clay core and clay blanket may also play a significant role in its anisotropic behaviour. This paper presents the drilling, sampling and testing program in the existing earth fill dams. It also presents the results from laboratory tests that include Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), one-dimensional consolidation oedometer tests, direct shear tests, and isotropically consolidated undrained triaxial tests. The laboratory results would be used to investigate the operating mechanisms of slope movements in an existing earth fill dam.
