An approach is developed for estimating the responses of a tunnel with multiple flexible
joints under fault movements. Initially, a new simplified mechanical model of flexible joints is …

Longitudinal deformation of shield tunnels consists of a combination of both bending and
shearing, which is characterized by the opening of the joints and the dislocation between …

Owing to a change in construction method, the existence of a reinforcement section, or a
settlement joint, an existing tunnel is likely to have discontinuities in its longitudinal stiffness …

To estimate the tunnel response induced by a new tunnel excavation underneath,
theoretical solutions are proposed in this study. The overlying tunnel is idealized as an …

Tunneling beneath adjacent in-service tunnel can generate displacement of soil, causing
adverse impact on the in-service tunnel. Many previous researches simplify the in-service …

The monitoring of longitudinal settlement of tunnel linings plays a great role in the preventive
maintenance due to the significant effect of settlement on degradation of the serviceability of …

The surcharge load at the ground surface inevitably breaks the original equilibrium state
between the underneath tunnel and the surrounding soil, which will impact the service …

In this paper, we study the effects of the shield tunnel construction on the deformation of an
existing pipeline parallel to and above the new shield tunnel. We propose an analytical …

As the requirement for underground space is growing mainly in metropolitan cities, building
a new underground tunnel in the locality of the in-service tunnel is one of the most common …

The settlement performance of an immersed tunnel in the Hong Kong–Zhuhai–Macau
Bridge (HZMB) transportation project is described. The geological profile underlying the …
