| Abstract: | This paper deals with prediction of collapse settlements due to saturation of rockfill, mainly in embankment dams. After some brief considerations about the physical basis and the practical importance of the phenomenon, a research program on this subject developed in LNEC is presented. Using non linear elastic models (and adequate loading and unloading-reloading criteria) whose parameters are quantified by laboratory tests and data from a field test, it is concluded that is possible and reliable to predict collapse settlements due to saturation of rockfill embankments. As a result of a parametric study the relative importance of the different parameters in the model is analyzed. |
