Influence of curvature change on soil arching effect in underground space development [PDF]
E3S Web of Conferences, 2021 This paper mainly studies the behavior of axisymmetric radial interaction between soil and structure under radial stress. Considering the possible factors in the interaction, such as the soil arching effect caused by the finite curvature, a simplified ...

Numerical investigation into the failure of a micropile retaining wall [PDF]
, 2017 The paper presents a numerical investigation on the failure of a micropile wall that collapsed while excavating the adjacent ground. The main objectives are: to estimate the strength parameters of the ground; to perform a sensitivity analysis on the back

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.

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
