CONSOLIDATION AND CREEP OF SOILS IN PLANE-STRAIN CONDITIONS

Rheological relationships expressed by families of strain isotaches have been introduced into the combined system of equilibrium and diffusion equations so that at any time of the consolidation the strain speeds correspond to strain isotaches. The plane-strain earth bodies are discretized by the network of triangular finite elements with 12 degrees of freedom. When, in the late phase of the primary consolidation, the excess pore pressures approach zero, the procedure ceases to give reliable results. Further development of displacements can be computed on the assumption that the secondary consolidation occurs at constant effective stress state. The corresponding computer program has been applied to geological, drainage and boundary conditions of a test embankment built on very soft marshy soils. The results have been compared with field measurements of pore pressures and displacements. The comparison has proved that the applied joint solution offers an adequate tool for predicting the behavior of non-linear viscous soils loaded by road embankments. In soils that exhibit effects of the previous secondary consolidation, the initial creep speed influences the forecast of settlements and of excess pore pressure dissipation.
