In this video, we explore how surface shape errors in the main bearing of a Tunnel Boring Machine (TBM) influence vibration levels, structural stability, and long-term operational performance. The study integrates dynamic modeling, simulation, and experimental verification to uncover how geometric imperfections lead to vibration excitation, load redistribution, and potential failure risks.

What You’ll Learn

Impact of surface shape errors on TBM bearing dynamics

How localized deviations trigger vibration modes

Simulation methodology and experimental validation

Influence of error amplitude and wavelength on vibration response

Engineering implications for TBM design, maintenance, and reliability

Who This Helps Ideal for researchers, mechanical engineers, tunneling professionals, and students studying machinery vibration, tribology, or reliability engineering.

How a tunneling machine works. SR99 Tunnel Project. The SR 99 tunneling machine (Bertha) was designed specifically for the ground conditions beneath Seattle. The short video above shows how the machine dug the tunnel. The slurry pressure system is designed to work with the variety of different soil types found in Seattle. Safety initiatives include injecting excavated soil with chemicals and using slurry pressure to prevent ground collapse. The new design allows cutter disks to be inspected and replaced from within the cutter head. This eliminates supplementary construction processes and allows the work to be completed safely at atmospheric pressure. Above-ground safety is of paramount importance because the machine will tunnel directly beneath a city. As such, the tunneling machine features a range of safety features. The tunneling machine has been split into sections weighing as close as possible to 900 tons, the maximum allowed under local weight regulations, in order to minimize the number of sections and speed up the assembly process in Seattle.

Bertha. Tunnel boring machine. Bertha was a 57.5-foot-diameter (17.5 m) tunnel boring machine built specifically for the Washington State Department of Transportation's (WSDOT) Alaskan Way Viaduct replacement tunnel project in Seattle, Washington, United States. It was made by Hitachi Zosen Sakai Works in Osaka, Japan, and the machine's assembly was completed in Seattle in June 2013. The machine completed its tunneling on April 4, 2017 and was fully dismantled and removed from the tunnel on Aug. 23, 2017.
