    • 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.
