A New Unified Solution for Circular Opening considering Different Strength Criteria and the Postpeak Elastic Strain Form

A New Unified Solution for Circular Opening considering Different Strength Criteria and the Postpeak Elastic Strain Form

The strength criterion is an extremely important basis for evaluating the stability of surrounding rock and optimizing the support pressure design. In this paper, nine different strength criteria are summarized and simplified based on the reasonable assumption. Then, a new unified criterion equation...
