The invention discloses a tunnel boring machine returning back disassembly method. The tunnel boring machine returning back disassembly method is characterized in that the tunnel boring machine returning back disassembly method comprises the followingsteps of (1) dismantling cutter head edge blocks, (2) disassembling a drilling machine and an arch frame installing device system, (3) dismantling side shields/a top shield, (4) returning back of a tunneling section, (5) returning back of a stepping section, and (6) disassembling a complete machine. The tunnel boring machine returning back disassembly method has the following advantages that (1), a disassembling hole chamber for expanding a fracture surface and anauxiliaryconstruction channel arranged for construction of the disassembling holechamber are eliminated, the problems that under the condition of great depth, the auxiliary channel is excessively long, construction periods of the auxiliary channel and thedisassembling hole chamber are long and the cost i
