Instrumentation of a reconditioned robbins tunnel boring machine - 106th Street Tunnel

摘要

Future accelerator projects at Fermilab may require the construction of tunnels in the northern Illinois bedrock. To understand how tunnel costs might be reduced we investigate the details of conventional tunnel boring machine (TBM) operations in an on going tunnel project. This may allow us to gain insights as to how we might increase the reliability and productivity of current TBM operations. Ultimately this should lead to lower tunneling costs. We describe instrumentation that was used to measure the parameters of this TBM operation.
