Analysis of Slurry (Mix shield) TBM Ground Deformation Control during the Queens bored tunnels project in New York City

Prof. Mike Mooney from Colorado School of Mines, USA will hold a guest lecture in the framework of SFB 837 about 'Analysis of Slurry (Mix shield) TBM Ground Deformation Control during the Queens bored tunnels project in New York City'.

The first part of the presentation will give an overview of the Colorado School of Mines. A summary of the research projects currently being conducted is also included.

The second part of the presentation will focus on recent research into slurry TBM control of ground deformation observed on the Queens bored tunnel project in New York City.
Four closely spaced and near surface transit tun-nels were excavated using two me-chanically identical Herrenknecht mix shield TBMs. The talk will describe the Queens bored tunnels and obser-ved deformation, present the observed TBM behaviors and the results of com-putational modeling.
