Experimental study on the effect of loading rate on the strain energy accumulation and release during the weakening process of circular-tunnel
Abstract The weakening of circular tunnels is a global problem that has not been resolved satisfactorily. In the tunnelling process, surrounding rock of circular-tunnel performs a process of “excavating → weakening → continuous excavating → weakening strengthens”. Different rates of excavation affec...
