Cable bolt bearing capacity - an in situ parametric study
Original language description
The study presents the behaviour of CRR system during pull out test which is usually used in the carboniferous rock mass in the Czech part of the Upper Silesian Coal Basin. Series of 28 pull out tests were performed on 3 m long cable bolts with various combinations of borehole diameters and bonding lengths for understanding this behaviour. Boreholes were drilled into a solid rock mass consisting of fine-grained sandstone to guarantee similar conditions during pull out tests. Video inspection and measurement of boreholes diameters were performed to determine their quality and real diameters. Three characteristics were observed from pull-out tests results: ultimate pullout load, displacement of the end of bolt and system stiffness. Numerical modelling byFEM was used to determine stiffness of the CRR system for variable bolt/borehole ratios and bonding lengths each under constant load. Linear elasto-plastic model and mohr-coulomb model were used for cable and resin-rock respectively. The
