Comparative Analysis of Two Kinds of Support Structure in Jointed Rock Tunnels: Rock Bolts and Steel Arches

Rock bolts and steel arches are common methods of support used in tunnel engineering. To compare the support efficiency of rock bolts and steel arches, numerical simulations were conducted using discrete element software to analyze the mechanical response characteristics and tunnel stability of support systems. Firstly...

Study on the Influence Law of Tunnel Primary-Support Arch Frame on Rock-Bolt Support Function

This study reviews the development of research on systematic-rock-bolt effectiveness in soil tunnels and clarifies the mechanism of rock-bolt inefficiency. Field statistics show that rock-bolt axial forces in soil tunnels are generally low or even compressive, especially at the arch crown, indicating limited contributi...
