Abstract: The shear strength of sand is important to the design and modeling of shield tunneling, and the tangential adhesion strength is a key parameter when determining the pressure gradient along the screw conveyor, the clogging ...

Abstract: Design formulas for placed block revetments are evaluated. The various formulas, as published in literature, have a different background or are based on different experiments. Most formulas are based on an analytical ...

Abstract: Tunnel construction in interaction with deep foundations is often a matter of concern in urban areas. However, a great deal of uncertainty is still evident in the differences between regulations for minimum tunnel clearance ...

Abstract: This paper presents two modifications to the traditional formulation of the load-transfer method; a distinct unloading path is defined for the load-transfer functions, and the displacement variable is modified to consider ...

Abstract: This paper presents an improvement on a previous model for predicting the Marsh funnel (MF) test that is used in slurry shield tunneling for evaluating the rheological properties of bentonite slurries. The improvement ...
