| 摘 要： | 基于统一强度理论导出圆形水工隧洞岩石抗力系数的计算公式。从该公式中不仅可得到以往的一些结果,还可得到一系列新的结果。这些新结果可以定量考虑岩石的中间主应力效应,因而能灵活地应用于各类岩石。

| Abstract: | Based on the unified strength theory,the formula for calculating rock resistant factor in circular hydraulic tunnel is derived.This formula can give some results obtained by previous formulas,and a series of new results which can consider the intermediate principal stress effect.Thereforei,t can be applied to more situations of rocks. |
