mm, SA = 3210m . （ 4） The calculation of anchorage body and rock mass anchoring length anchoring length should not only meet the requirements which the bond force of formation on mortar and the bond stress of mortar on steel, but also meet the requirements that the Structure design codes the Minimum anchoring length. (4) In the formula: al is the anchoring length。 D is the diameter of anchorage body。 rbf is the bond strength eigenvalue of layer and anchorage body, through the experiment or local experience sure, or according to the standard to selection ( this engineering’s rock mass uniaxial pressive 2 2 2 21 1 12 0 9 ta n ( 4 5 ) 2 0 9 0 . 2 1 7 1 7 5 . 7 7 /2 2 2 2eaaE H K k N m           costkak HN 2aSyNA f1akarbNl Dfstrength is aMP , belong to soft rock, rock mass structural plane development, rbf take 300 aKP )。 1 is the bond working conditions coefficient of anchorage body and layer (permanent anchor take ).

According to the calculation, al ， take al =. The construction technology and key points of anchor The anchor’s construction technology is as follows: buildup scaffold—— excavate and clear up the slope surface—— measures to fix position—— drill hole—— washing hole—— bolt put in a certain place—— grout—— colligation the end of the anchor—— flushing the slope surface——pouring frame space—— Spray seed （ 1） This slope belong to rocky slope, after excavate the slope 10 cm to the underside of the frame space, set bolt and pouring frame space, then spray grass or seeds after borrowed soil 20 cm in the frame space. （ 2） the slope should be payed attention to clean up, when construction. The anchor should be placed after wash hole, then put pressure () and grout. After the mortar fully solidification, colligation steel, castinplace。
