Abstract

Abstract

Geofabric-composite bolt is a new anchoring reinforcement structure used in cataclasite.A landslide control project was used as a platform to carry out pull-out test of two sorts an chorsfull length bonded and prestressed anchors, to verify the feasibility of using geofabric-composite bolt to strengthen cataclasite.The field test results showed that geofabric-composite bolt could solve the problem of grouting-mud leakage in cataclasite.The data regression analysis showed that reinforced effect and ballooning effect of geofabric could adjust the interface stress between anchoring body and cataclasite and the pollout force of the anchoring system was improved.
