Quasi-rectangular shield tunneling is a cutting-edge trenchless method for constructing metro tunnels with double tubes, owing to its advantages in saving underground space and reducing ground disturbance. However, the conventional quasi-rectangular shield tunneling method is ...
Advancing Shallow Tunnel Construction in Soft Ground
The Pipe-Umbrella Box Jacking Method
Fire-Retarding Asphalt Pavement for Urban Road Tunnels
A State-of-the-Art Review and Beyond
With the rapid urbanization and development of metropolises, urban road tunnels have been constructed at an increasing rate, significantly alleviating urban traffic pressure, and improving urban resilience. Fire hazards have become a major threat to modern road tunnels due to ...
Distributed fiber optic sensors for tunnel monitoring
A state-of-the-art review
Backfill grouting plays a vital role in shield tunneling. This paper aims to present a comprehensive review of the development and progress of backfill grouting materials specifically designed for shield tunneling. Initially, the various components of grouts, such as pozzolani ...

Pipe jacking has been the dominant trenchless technology for constructing small (\2 m) to medium-diameter (\4 m) tunnels. Uncertainties and construction difficulties increase significantly when the diameter of the tunnel exceeds 4 m. This paper presents a case study of the lar ...
With the acceleration of urbanisation in China, land shortage has become a severe problem in metropolises. As the medium and shallow underground space in central urban areas has been developed to a matured or even saturated extent, development of deep underground space (DUS) b ...
