The accurate assessment and effective management of deep excavation risk have faced
longstanding challenges due to the highly complicated and uncertain construction process …

In this paper, we conducted a series of model tests aimed at studying mechanical behavior
of a shield tunnel structure under the combined action of external soil-water load and …

The history of tunnel boring machine (TBM) tunnelling dates back to nearly 50 years ago.
Due to high construction cost, the investigation on TBM performance is regarded as one of …

With the development of subways and tunnels, health monitoring of these structures are
more and more important. Terrestrial laser scanning is an essential highly accurate …

The mechanical properties of high-stiffness segmental joints (HSSJs) in deep-buried
drainage shield tunnels bearing high inner water pressure are different from those of …

Existing design guidelines for concrete hinges consider bending-induced tensile cracking,
but the structural behavior is oversimplified to be time-independent. This is the motivation to …

This paper presents an analytical solution derived with force method for the internal forces in
the ring lining of maglev train tunnels, which are typically in a circular section and shallowly …

Water inrush from the excavation face often occurs in the current shield construction of metro
tunnels. In this study, the discontinuity of shield tunnel lining and the interaction between the …

At present, there is no clear design standard for segmental joints of large-diameter shield
tunnels under high water pressure. In this paper, a theoretical calculation model for the …

The upward shield method in horizontal tunnels has the advantages of small ground space
occupation, low construction cost, and short construction period, which expresses …
