A Variable Stiffness Method Application to Tunnel Support

Abstract:

This paper focuses on finding a more effective bolting design method. Stress and displacement of variable stiffness beam were calculated by using material mechanics, variable stiffness bolting designs was simulated using FLAC5.0 software. The calculation indicates that the maximum displacement of a variable stiffness beam is less than that in a constant stiffness beam, while same material quantity is used; and proper variable stiffness designs can improve the bolting effect while same total quantity of bolts is used according to the simulations.
