Abstract: Provided is a TBM tunneling test bench for microwave-assisted rotary rock breaking including a tunneling test bench body and a microwave-assisted rock breaking system, wherein the tunneling test bench body includes a base, a turnover bracket, a movable bracket, turnover oil cylinders, a pushing oil cylinder and a cutter head; the turnover bracket is hinged to the base; the turnover oil cylinders are connected between the base and the turnover bracket; the movable bracket coaxially sleeves the turnover bracket; the pushing oil cylinder is connected between the turnover bracket and the movable bracket; the cutter head is coaxially located in the movable bracket, and rotates freely; cutter head rotation driving motors are mounted in the movable bracket; the microwave-assisted rock breaking system is mounted between the movable bracket and the cutter head; and a rock sample bearing and placing box is arranged on the turnover bracket on an opposite side of the cutter head.

Abstract: A hard rock tunnel boring machine combining microwave heating with high pressure water cutting for assisting in rock breaking includes a tunnel boring machine body, a microwave heating assisted rock breaking system and a high pressure water cutting assisted rock breaking system, wherein the microwave heating assisted rock breaking system is arranged on the tunnel boring machine body, and is used for heating and cracking a rock; and the high pressure water cutting assisted rock breaking system is arranged on the tunnel boring machine body, and is used for performing hydraulic cutting on the rock. A rock breaking sequence lies in that the microwave heating assisted rock breaking system is used for heating and cracking the rock, then the high pressure water cutting assisted rock breaking system is used for performing hydraulic cutting on the rock, and finally, the tunnel boring machine body is used for squeezing and breaking the rock.

Abstract: The present invention belongs to the technical field of tunnel surrounding rock supports and discloses a tunnel surrounding rock supporting method and system based on a tunnel field deconstruction and reconstruction theory. The tunnel surrounding rock supporting method based on the tunnel field deconstruction and reconstruction theory comprises the following steps: establishment of a tunnel field, deconstruction of the tunnel field and reconstruction of the tunnel field. In the tunnel surrounding rock supporting method based on the tunnel field deconstruction and reconstruction theory provided by the invention, through reconstruction of the tunnel field, the energy storage capacity of a rock and soil mass can be improved.
