Abstract: Encountering obstacles or excessive cutter wear in shield tunneling often result in shutdown of the shield machine, and intervention techniques are extremely critical. Based on collected documents related to this, this paper summarizes the basic concepts of intervention in the shield chamber and analyzes the application scope as well as the advantages and disadvantages of intervention at atmospheric pressure and pressurized conditions. Combined with typical cases concerning intervention in shield chambers, the experiences and technical key points are systematically summed up and future developments in China regarding interventions in shield chambers are discussed.
