【摘要】 基于统一强度理论,本文推导得到围岩抗力系数计算公式,该公式具有可以考虑中间主应力的影响以及修改参数后可以退化为其他围岩条件或者其他强度理论条件下的围岩抗力系数计算公式等优点,具有较强实用价值.更多还原

【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.更多还原
