Funded Activity Summary

The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, and so often expensive deviations have to be made to tunnels to avoid going near existing ones. The proposed research will provide numerical tools to allow prediction of loads induced into rock bolts by nearby tunnels, leading to more economical and safer tunnel design.
