等向固结过程中软粘土微观孔隙结构演化机制的定量研究

hrought the consolidation tests of the original state of soft clay under different isotropic consolidation pressures, the SEM images of all samples of before and after test are prepared, the image processing technology of IPP is used to analyze the indicators of the pore structure and regularities of distribution which are size,quantitative, porosity and surface fractal dimension, roundness. The results showed that: with the increase of the consolidation pressure, the porosity gets smaller, the value of surface fractal dimension shows normal distribution,and the normal distribution curve pan left,the roundness value of pore shows the form of exponentially decreasing function.
