摘要
Representative sample of soft soil in Tianjin Binhai new district under different consolidation pressures are made by chill-sublimating and SEM(scanning electron microscopy). The change of pore structure parameter of sample SEM images under the applied consolidation stress level is systematically analyzed and the integrity and average equitability of pore distribution is studied with the simple plane fractal (Dp), and Pore Structure Factor (PSF) is presented which can reflect the scale, shape, distribution, orientation of pore. The research indicates that there is a fine corresponding relationship between structural parameters of internal pore and external loading. The internal characteristics of void are quite different before and after structural yielding pressure.
