Analysis on anchoring force of full length flexible pressurized grouting bolt

The flexible pressurized grouting bolt is a new full length anchored bolt.Due to the complexity and variety the rock and soil mediums,it is difficult to determine the anchoring force.With the summarization of the bolt failure formation,the paper analyzed the anchoring force of thethe flexible pressurized grouting bolt and derived the calculation and analysis method of loading capacity,which could provide the theoretical basis for the design,test and further application.
