Abstract
One of the characteristics of soft rock that contains clay and engineering geology is water swelling and.disintegration. The fractal model of slate disintegration is established by Gate Gaudin Sehuhmann distribution function, representative slate samples are chosen to perform laboratory tests of slaking, and the fractal dimension value of slate disintegration change law with time is obtained. The results show that absorbing water and disintegrating progress of slate is also a progress that fractal dimension of slate scrap change successively, when disintegrating of slate arrived to some extent, grade of scrap of slate disintegrated is no more change, fractal dimension of scrap of slate disintegrated incline to a critical value. The disintegration of slate has lag phenomenon in time. The initial disintegration time and the maximum disintegration fractal dimension of rocks are different because of the different microstructure and material composition.
