Analytical prediction of ground movements due to circular shaft construction in clayey soils
Canadian geotechnical journal (Print), 2023 With the rapid expansion of urbanization, shafts are needed to provide access to tunnelling projects or be utilized for permanent works. Their construction causes ground movements, affecting nearby foundations and buried infrastructure.

Analytical Modeling for Mechanical Straightening Process of Case-Hardened Circular Shaft
Applied Mechanics, 2023 Straightening has to be carried out in order to ensure the straightness of a shaft, as distortions exceed the tolerance limit. Since the straightening load is typically large enough to produce plastic and residual deformation, repeated straightening ...

Subsurface ground movements due to circular shaft construction
Soils and Foundations, 2019 The rapid development of modern metropolises has led to a shortage of surface space and, in response, engineers have pursued alternatives below ground level.
