TL;DR: In this paper, the authors developed an improved analytical solution to evaluate the effects of adjacent excavations on a pile using a Timoshenko beam resting on a Vlazov foundation, based on which the pile shear characteristics and inhomogeneity of multilayer soils are further considered.

TL;DR: In this paper, a rational modeling procedure for the damage mechanism and serviceability of shield tunnel under unloading based on damage constitutive model of concrete, the nonlinear damage characteristics of concrete material are considered.

TL;DR: In this article, a positive/negative decomposition of stress tensor in energy norm is introduced to consider the asymmetric tensile/compressive material behavior of concrete, and a bi-scalar damage constitutive model of concrete is developed in turn.

TL;DR: In this paper , an analytical model for calculating the additional response of the segmental lining under asymmetric thrusts was established, where the shield tunnel was simplified to a Timoshenko beam on Winkler's foundation.

TL;DR: In this article , a damage-based analysis method for investigating the ultimate bearing capacity of shield tunnels is proposed, where a bi-scalar elastoplastic damage constitutive model based on energy-based stress decomposition is introduced to describe the damage and deterioration behavior of concrete materials.
