Construction Technology for TBM Card Machine Trapping under Unfavorable Geological Conditions of Rock Burst and Altered Rock
With the rapid development of the economy and society,tunnel engineering is flourishing in China.Tunnel Boring Machine(TBM)combined with drilling and blasting method is currently a common-ly used construction method for ultra long mountain tunnels.In adverse geological conditions,hard rock tunneling machines are prone to jamming,and in severe cases,engineering accidents may even occur.In order to cope with the possible jamming situation mentioned above,a technology for dealing with TBM jamming under adverse geological conditions such as rockburst and weathered rock is proposed based on the construction of water conveyance tunnels using the TBM method under construction.The key points of treatment,specific construction methods,and control processes are emphasized.The implementation of this construction technology and the application of TBM to overcome difficulties provide valuable cases and references for dealing with similar engineering equipment in the future.
