Fire is a significant hazard to the safe operation of tunnels, causing extensive damage and
deterioration to the lining. This research proposed a prototype test of a shield tunnel …

Fiber reinforced concrete has been a widely applied durable material in ground structures or
as the primary support in underground structures in the form of shotcrete. Whereas, fiber …

In high-performance concrete (HPC) subjected to high temperature during tunnel fires, the
build-up of vapor pressure due to dehydration of the cement hydration products cannot be …

Though fibres are being used in concrete structures for a couple of decades, the use of
polymeric Synthetic Fibres (SyF) such as Polypropylene Fibre (PPF), Polyethylene Fibre …

The longitudinal joint is the most critical component for determining the mechanical
response of concrete segmental linings. Existing longitudinal joint models are mainly …

Investigating fire effects is a continuing endeavour in the research and practice communities
concerned with the design and safety of shield tunnels. This paper aims to provide a …

The seismic response of a tunnel lining structure is essential for its safety design and
construction. The objective of this study is to investigate the seismic response of a tunnel …

As a significant infrastructure hazard, fires in tunnels have brought about a great deal of
economic and social losses each year. From a holistic tunneling design perspective, it is …

Very few micromechanical models are available for hybrid fiber reinforced concrete (HFRC),
although it has been widely applied in many structures. To quantitatively predict the effective …

Longitudinal bending stiffness efficiency (LBSE) is a key parameter for analyzing
longitudinal behavior of shield tunnel. The LBSE is defined as the deformation ratio of a …
