| Abstract: | Based on the unified strength theory,the formula for calculating rock resistant coefficient is given in the paper,which can be adopted to consider the intermediate principle stress effect and to obtain rock resistant coefficient in other situations or strength thoeries simply by assumed the parameter in the formula.So the formula can be applied in kinds of rock conditions. |
