Abstract

On the basis of damage theory，combing effective stress principle with Lemaitre¢s strain equivalence assumptions，an expression of effective stress under stress and seepage coupling condition was established. Assuming that the micro-unit strength obeys Weibull distribution，a statistical damage constitutive model considering pore water pressure was established. Comparing the test data with the results obtained from the statistical model，the new model can fit the test data well，showing the validity and feasibility of the new model. Then the relationship between pore water pressure and model parameters，damage characteristics were discussed，and it will provide good reference for safety analysis of rock engineering under stress and seepage coupling condition.

Key words： rock mechanics pore water pressure statistical damage effective stress theory damage evolution
