Abstract
The present application provides a kind of coal rock sample damage evaluation method based on strain, electronic equipment and storage medium, by obtaining coal rock sample strain parameter, based on the damage variable of the damage variable of hoop strain increment and the damage variable of crack strain increment calculated from the coal rock sample strain parameter;According to the damage variable of the damage variable of hoop strain increment and the damage variable of crack strain increment, the damage variable of comprehensive strain increment is calculated;Based on the damage variable of multiple comprehensive strain increments arranged in time sequence, the damage variable increasing speed is obtained;According to the damage variable increasing speed, the coal rock sample damage evaluation result is output, improve the accuracy and comprehensiveness of damage variable description, further improve the scientificity and reliability of damage evolution evaluation, and quantitative description and evaluation of damage reduction can be realized simultaneously.
