heal.abstract	A set of empirical relations is developed for the prediction of permanent shear strain and excess pore pressure accumulation during undrained, cyclic triaxial loading of sand. For this purpose, a multi-variable regression analysis is performed on results from 179 isotropic and anisotropic tests, using as variables the initial stresses, the cyclic shear stress amplitude, the volume density and the applied number of load cycles. The relations provide the means for simplified computations of settlements and bearing capacity of foundations. In addition, they can be used as reference for the calibration of constitutive models aimed at the prediction of cyclic sand response.	en
