Abstract
A tertiary cooperative compression yielding and energy-absorbing support mechanism. The compression yielding and energy-absorbing anchor cables play a basic support role, and the circumferential compression yielding device can make the primary support compression yielding arch frame have a constant resistance deformation in the circumferential direction, while the primary support compression yielding arch frame and the secondary lining steel arch frame have a relative dislocation movement in the radial compression yielding device, and the tertiary compression yielding and energy-absorbing structures are cooperated with each other to adapt to the over-meter large deformation movement of the surrounding rock.
