Zusammenfassung: | The invention discloses a tunnel deformation control system with high strength and super toughness and a construction method thereof. The system comprises an active supporting layer, a yielding deformation layer and a main bearing layer. The active supporting layer is formed by hanging a net and spraying concrete, and the hanging net is fixed to the inner wall of the tunnel through anchor cables and anchor rods. The yielding deformation layer consists of a filling material and a high-strength spring; the main bearing layer is made of corrugated plates made of materials with high longitudinal and transverse strength and rigidity. The high-strength and high-rigidity corrugated plates are arranged to replace a traditional steel arch structure, and the defect that an existing supporting structure is insufficient in strength and rigidity is overcome; secondly, due to the integral structure type yielding deformation layer, the problem of local stress concentration caused by surrounding rock deformation is solved, a |
