The deformation of a fill made of cement-mixed soft marine clay was evaluated based on the results of special triaxial compression tests. Simulating the stress path and loading time history in the field, a sequence of anisotropic compression and four days drained creep was repeated, lasting 44 days in total. The axial strains were measured locally. The test results were consistent with the measured compression of the fill but standard oedometer test results over-estimated it. Development of a high stiffness zone around the creep stress state and creep deformation is a key in the deformation prediction. A high stiffness behaviour of the fill, when loaded after drained creep with curing, is suggested.
