Abstract:

The identification and classification of swelling rock are important for its research. A new criterion is proposed that in which the montmorillonite content is a basic control index; the dry saturated water-absorptivity, limit swelling quantity, limit swelling power are main indices. And it has been used for analyzing an actual engineering.

Key words: rock mechanics, swelling soft rock, differentiation criterion, gradation indices
