| 摘 要： | 根据岩石和围岩的蠕变机理以及软岩流变控制原则，建立了一个软岩最优支护计算方法，它能求出软岩支护的两个重要参数，即最优（小）支护力和围岩最大允许变形量。最优支护可以达到新奥法提出的既安全又经济的最佳支护状态。文中用两个工程实例验证了所提出的方法

| Abstract: | Based on the creep mechanism and the rule of controlling creep , this paper gives a method of calculating optimum support for soft rock. By this method the optimum support pressure and the allowable maximum deformation in surrounding rock can be calculated. The optimum support means a condition which is both safe and economic as suggested by NATM. Two examples are given to verity the established method. |

| Keywords: | support for soft rock creep support pressure deformation |
