Consideration is given to the prediction of undrained movements which may occur due to contained yielding beneath embankments on muskegs. The study shows that insignificant improvement in the predicted undrained movements can be expected by assuming the soil to be an elastic cross-anisotropic material unless the independent shear modulus is measured. All predictions were made using the finite element technique and assuming the soil to be an elastic isotropic yielding material. The settlement predictions are in good agreement with the recorded construction movements of the two case records studied.The first analysis clearly shows that the yielded zone is restricted to a soft clay layer immediately beneath about 20 ft (6.1 m) of peat and marl. The predictions show that berms have a beneficial effect in containing this zone and reducing differential settlement. Horizontal movements are significant in comparison with the vertical movements except near the centerline.In the second case, analysis of a shallow peat layer underlain by stiff clay shows that the predicted settlement and shape of yield zone are largely dependent on whether the lower boundary is assumed perfectly rough or shearless.
