Abstract:Firstly,anchorage mechanism of composite rock-bolt was discussed. The special characteristics of the analytical solutions of shear stress and axial stress distribution were developed. Secondly,relying on the anchoring projects of the cliff of Jiaohe Ancient City,the construction techniques have been systematically optimized based on understanding general situation of the study area and anchorage mechanism of the composite rockbolt as well as failure modes of the cliff,including the location of anchor hole,hole-creating,lifting rock-bolts,installing rock- bolts,grouting,installing anchor devices,blocking the anchor holes,imitation of ancient surface,and curing the rock-bolts. The research results provide scientific basis for popularizing this new type rock-bolt for the preservation projects of cultural relics in the arid-semiarid regions,and it has a referential meaning for similar anchoring projects.
