This paper describes the key influences of yaw excavation loadings on ground displacement
and segmental stress for a curved shield tunnel. The influences are investigated through …

This paper focuses on the ground settlement induced by the construction of a curved shield
tunnel. Ground loss and construction loadings are the two factors causing ground …

The construction of non-circular tunnels at shallow depths is becoming increasingly common
to efficiently use excavation space. However, the stress concentration and ground …

In general, twin noncircular tunnels may cause high stress concentrations and large
settlements because of the strong interaction between tunnels and their noncircular shape …

According to the excavation methods of tunneling, a damaged zone may be developed in
the rock mass around the tunnel, the mechanical properties of which can be significantly …

In the case of sudden surcharge loading, shallow shield tunnels in areas with soft soil
experience substantial deformation responses. It is very important to understand the different …

The longitudinal behavior of a shield tunnel is essential for analyzing its deformation and
internal forces under surcharge. This study involved the design and construction of a …

The excavation of a tunnel using a shield machine induces an impact on the tunnel lining
responses and settlements. Three-dimensional finite difference calculations of twin …

In this article, an alternative numerical procedure to calculate displacements and stresses of
supported circular tunnels is proposed, considering the whole process of tunnel …

A unified displacement function is used as the displacement boundary condition of the cross-
section of each tunnel, which can be used to capture the asymmetrical deformation …
