Robbins Lecture

Non-Circular Tunneling in Rock: A New Way Forward
Presented by Brad Grothen P.E., Robbins Technical Director

Abstract: When a flat roadbed is needed, is a circular TBM the best way to go? In this presentation, Robbins Technical Director Brad Grothen will discuss a mechanical boring machine currently being used in the mining industry for a rectangular tunnel cross section, and the potential for use of this machine in civil tunneling. Grothen will also look at emerging technology to demonstrate that by using non-circular TBMs, a flat invert can be safely and economically created in one pass.
