Book: Rock Engineering for Concrete Dam Foundations

The TBM Face Support Pressure Assessment Tool is an advanced web-based engineering application developed to evaluate tunnel face stability and determine the required support pressure for Earth Pressure Balance (EPB) and Slurry Shield Tunnel Boring Machines (TBMs). The tool integrates several internationally recognised analytical approaches and provides engineers with a transparent framework for assessing face stability, groundwater control, blow-out risk, and geotechnical unc

Schleiss introduced a comprehensive mathematical framework for the interaction between tunnel lining and surrounding rock mass in pressure tunnels and shafts in his PhD thesis (Schleiss, 1986). Building on this foundation, he went on in the early 1990s -while serving as Head of the Hydraulic Structures Section at Elektrowatt Engineering Ltd. (now AFRY) in Zurich - to develop one of the most widely recognised methods for the design of reinforced concrete (RC) linings for press
