| Abstract: | Considering the supporting work on a section of Jinping II Diversion Tunnel under extremely intensive rock burst geological condition,some appropriate improvements on the existing swelling pre-stressed bolts were performed so as to meet the requirements of rapid driving of TBM,i.e.such improved bolts need to be quickly installed and worked effectly when applied on rock burst and collapse sections. |
