DOI: 10.1016/j.tust.2020.103346
Abstract: Abstract The non-circular tunnels, for example the quasi-rectangular tunnel, may generate a considerable shear force at their shoulder joints owing to the geometry effect. To investigate the shear force effect on the mechanical behavior (e.g.,… read more here.

DOI: 10.1016/j.tust.2021.103834
Abstract: Abstract In the context of segmental concrete linings for tunneling, segmental joints are the most vulnerable parts of the lining. Most existing segmental joint models cannot evaluate the full mechanical behavior of segmental joints from… read more here.

DOI: 10.1155/2017/2829783
Abstract: Impact loads generated by derailed trains can be extremely high, especially in the case of heavy trains running at high speeds, which usually cause significant safety issues to the rail infrastructures. In shield tunnels, such… read more here.
