Abstract:Based on the test measurement,the electrical resistivity model of Lianyungang marine soft soil is established;and this model is applied to illustrate the change rule of microstructure of Lianyungang marine soft soil during creep. Furthermore,the soft soil creep value is estimated by the means of electrical resistivity indices. And then,the correlation between the microstructure and the creep is demonstrated;and the parameter M,integrative electrical resistivity structure factor,can well evaluate the creep value of marine soft soil. Applying the electrical resistivity model to study quantitatively the soft soil microstructure,this method will radically overcome some deficiencies of conventional microstructure method and greatly improve the operability and consistency of obtaining soil microstructure indices. Accordingly,a new method is presented to illuminate the change rule of microstructure of marine soft soil during creep and to estimate the creep of soft soil.
