ATS WEBINAR – Large Diameter EPB Operation to Control Settlement
October 23 @ 1:00 pm - 2:00 pm
Explore the scope and risks associated with large diameter EPD machines, including the specific requirements for large diameter TBM’s and the operational requirements to achieve tight settlement control.
The use of mega TBM’s for road tunnels or combined road and rail tunnels with an external diameter of greater than 14m is rapidly increasing. Up to 2019, there have been 39 tunnelling projects worldwide using mega TBMs. There is also a worldwide trend to use EPB machines, including in large diameter tunnels. There are a number of issues in scaling TBM operations from standard metro machines to mega TBM’s of greater than 14m. This presentation will cover specification requirements for the large diameter TBM’s as well as operational requirements to achieve tight settlement control.
