Face stability of shield tunnels considering a kinematically admissible velocity field of soil arching

Journal of Rock Mechanics and Geotechnical Engineering, 2022
Existing mechanism of simulating soil movement at tunnel face is generally based on the translational or rotational velocity field, which is, to some extent, different from the real soil movement in the arching zone. Numerical simulations are carried out

Influence of Rotations on the Critical State of Soil Mechanics [PDF]

, 2010
The ability of grains to rotate can play a crucial role on the collective behavior of granular media. It has been observed in computer simulations that imposing a torque at the contacts modifies the force chains, making support chains less important.

Pile-Spacing Calculation of Anti-Slide Pile Based on Soil Arching Effect

Advances in Civil Engineering, 2020
Anti-slide pile is one of the most frequently used measures in landslide control globally. Pile-spacing has always been determined by the load capacity of single piles or according to engineering empirical experience.

A calculation method of earth pressure on sheeting between two piles considering soil arching effect and intermediate principal stress

Shuiwen dizhi gongcheng dizhi, 2022
The classical theories of earth pressure are based on the M-C strength criterion, which do not consider the influence of soil arching effect and intermediate principal stress on earth pressure, so the theoretical earth pressures are significantly larger ...

Design of cylindrical plastic pipe linings to resist buckling due to collapse pressures [PDF]

, 2005
Flexible (non-bonded) polymeric sewer linings are used extensively to renovate both gravity and pressure pipes. Linings for both types of pipe are subject to collapse pressures, and in the case of gravity pipes this is the dominant source of loading ...
