Abstract

This paper concerns with the derivation of analytical expressions for such consolidation behaviors as settlements and pore pressures developed in embankments during and after construction. Basic assumptions involved in the analysis are that an embankment is constructed as a soil column in shape and that consolidation behaviors obey the concept of Terzaghi's onedimensional consolidation. Unlike recent regorous finite element approaches, analytical expressions are developed from a clear-cut point of view, aiming at simple and practical applications in the preliminary design as well as in analyzing field observation data. A few example applications showed that the present analytical approach on the whole yields good correspondence with settlements and pore pressures in actual dams.
