摘要
In this paper, SEM, settlement and void ratio of samples in different consolidation periods are obtained by laboratory experiments. Software WD-5 is used to process the SEM images of samples in different consolidation periods based on the simulation experiment. And then the fractal dimension of pore distribution is obtained. Finally the relative equation is established between degree of consolidation and fractal dimension. The results show that fractal dimension of pores distribution decreases with the increasing of settlement. There is a clear turning point at the time of 42.33 h in the consolidation. The results of the calculation are basically agree with the measurement in tests.
