DOI: 10.1016/j.tust.2017.05.010
Abstract: Abstract Segmental joints act as a weak link in the tunnel lining both in terms of structural responses (due to the lower stiffness and strength compared to the main segments) and the serviceability considerations (high… read more here.

DOI: 10.1016/j.tust.2018.03.029
Abstract: Abstract Segmental joints are vulnerable parts of the lining structure in precast shield tunnels, both from the structural (lower stiffness compared to main segments) and non-structural (potential water leakage points) perspectives. Previous works have focused… read more here.

DOI: 10.3390/app13105904
Abstract: Shield tunnels inevitably endure various forms of damage as their service times increase. Steel corrugated plates have been used extensively under multiple conditions and have proven effective in strengthening segmental joints, according to full-scale tests.… read more here.
