(1) A large-scale (500mm×500mm×480mm) three-dimensional testing system was developed for the simulation of rock bolting.This system has functions of loading, confining and measurement, with which the whole process of loading, deformation and failure of jointed rocks can be truly represented.To monitor the real-time anchoring force of bolt, the high-precision miniature ergometer was developed to measure the anchor end force and the dynamometric bolt based on fiber Bragg grating was made to get the multipoint anchoring force along bolt.A new method of making multiple joints was designed and the corresponding molds were fabricated.An ideal similar material of intermittently jointed rocks was developed.
