Abstract: Through grain-size analysis of scrap for soft rock that was produced during test of collapsing in laboratory and test of gradual collapsing in field atmospheric condition; it was found that absorbing water and collapsing progress of soft rock is also a progress that fractal dimension of soft rock scrap change successively. When collapsing of soft rock arrived to some extent, grade of scrap of soft rock collapsed is no more change; absorbing water and collapsing of soft rock stopped; fractal dimension of scrap of soft rock collapsed incline to a critical value. The critical value opens out fractal mechanics of soft rock when it swells and collapses after absorbing water. The above-mentioned conclusion exists a guidance significance to engineering.

Key words: soft rock, swell and collapse, fractal dimension, scrap
