| Abstract: | Some methods for anchoring rock mass are introduced. The following problems such as action mechanism between rock mass and anchoring cables, the effects of stress state of rock mass on the anchoring effectiveness, losses of the pre_stresses, the type of anchoring cable, the time of pre_stress action and the durability of anchoring cables etc, are discussed mainly. The authors' some viewpoints on above_mentioned problems are proposed for reference. |
