In the evaluation of safety for sliding of cohesive slopes and for bearing capacity on soft foundations, effect of progressive failure and strain-dependent instability have been special concerns instead of limit equilibrium approach. Some simple and practical methods of estimating foundation failure of clay deposits have already been proposed on the basis of field measurements and finite element analysis, by taking notice of the relationship between settlment (or surcharge load) and lateral deformation. In the present paper, results of field failure tests performed on full-scale model embankments of about 5-m in height are studied, comparing with finite element soultions on them, to examine the relationship between slope stability and lateral deformation of embankments. Procedures for safety control are then discussed for an actual earth dam with an inclined core of material having high water content, to prevent sliding and extreme deformation during construction.
