Abstract

The frequent occurrence of shallow rock mass peeling diseases in the roof of the grottoes reduces the stability of the grottoes? structure and affects the preservation of cultural information. The vertical anchoring technology，with low disturbance and high concealment，effectively restrains rock mass deformation and controls the disease?s development. This experiment selected 8，10 and 12 mm diameter Glass Fiber Bolt(GFRP) and Basalt Fiber Bolt(BFRP). The optimal aperture ratio was determined based on previous researches，and the bolt was inserted into the sandstone roof. Strain measuring points were placed at small intervals at the rod-slurry interface，and a cyclic loading mode was used for the field pull-out test. It was observed that the inverted anchorage system，using small diameter GFRP and BFRP，demonstrated interface coordination and deformation easing ability in the elastoplastic stage，and that the anchorage system with a 10mm diameter showed the best matching ability to the optimal aperture ratio. The inverted multi-stage grouting method exhibited a simple construction process and good performance. Compared with the previous test results，it can be seen that the ratio of ultimate load between the cliff horizontal anchoring system and roof inverted anchoring system with the same anchoring parameters is 1.90 times，the corresponding displacement ratio is 3.27 times，and the ratio of strain range is 3.26 times. The performance difference of the two anchoring systems is related to the difference of bolt insertion direction and grouting quality，etc. The relevant research results can provide support for the engineering application of micro-miniature inverted anchor bolt in sandstone flat roof.

Key words： rock mechanics cave temples roof of a flat cave micro-sized anchor inverted anchorage test methodology
