A RHEOLOGICAL CONSOLIDATION MODEL FOR SOFT CLAY WITH CONSIDERATION OF TEMPERATURE AND THE ANALYTICAL

Based on the four element rheological model, a rheological consolidation model for the Ningbo soft clay is established with consideration of the influence of temperature, and the analytical solution for the rheological consolidation of the saturated soft clay under instantaneous loading conditions is obtained by Laplace transform. Based on the rheological consolidation test results of soft clay in different temperatures, the parameters in the rheological Ningbo soft clay four element model are determined. And the theoretical values are compared with the experimental values. It is shown thatthe model can well reflect the rheological consolidation characteristics of the Ningbo soft clay,and the calculated results are in good agreement with the experimental results. The increase of the temperature leads to an increase of the permeability coefficient, and the pore pressure dissipates at the same time, leading to an accelerated consolidation.
