With the effects of high geostress and intensive dynamic disturbances in deep mining, the stability and safety of tunnels are seriously affected.
The optimization for U-shaped steel support is of vital significance and can solve the problems of cost reduction and tunnel instability.
Based on the perturbation equation, a coupled formula for U-shaped steel and the surrounding rock mass was proposed to evaluate the practical stability of a U-shaped steel support.
Through a numerical simulation method, the characteristics of U-shaped steel support can be obtained under coupled static-dynamic loading.
Furthermore, the field test was carried out and compared with the numerical simulation, which was discussed.
The results show that there will be a stress concentration when the contact area is small.
In addition, the concentrated stress will release with the increase in contact area.
With the increase in the lateral stress coefficient, the deformation exhibits a downward trend under static loading, indicating that the lateral stress is the dominant force driving the deep geostress activity.
The support requirement of this section of surrounding rock can be satisfied by a U-shaped steel group with 1.5 m spacing under dynamic disturbance.
