Abstract: Combined the consolidated project of Gaochang Soil Ruinsin Xinjiang Province, and directed toward the new type of geo-filamentbolt, the theoretical analysis of bearing capacity is done based on the Mindlintheory of fully grouted bolt. The site test results arecompared with the theory. In addition, the surface state and the failuremode are researched. The experimental study reveals that the geo-filament boltcan satisfy the consolidation requires of the earthen architecture site andthe change of the bolt surface through adding ribsaffects obviously the anchor force. The geo-filament bolt is proved to be an excellent materialfor the walls reinforcement of earthen architecture sites.
