| Abstract: | The achoring cable is a pulling force of component which adoping the pre-stress to resist the slide and the face pressure for steading the slope.It had a discussion about the anchoring cable on the different from strength of state and adoping the sorts of rock.At the same time we should notice the loss of pre-stress.It can adopt the high intensity and low relaxation of steel strand or excessed stretching to reduce the losing. |

| Keywords: | Pre-stress achcring cable loss of pre-stress |
