DOI: 10.1007/s11440-019-00806-w
Abstract: The failure mechanism and limit support pressure are essential factors for the stability assessment of tunnel face during shield tunneling. Previous studies were mostly based on the assumption that soil fails when the plastic limit… read more here.

DOI: 10.1016/j.soildyn.2019.105946
Abstract: Abstract Soil liquefaction induced by earthquakes not only causes settlement and lateral spreading of the ground, but also lowers the stiffness and strength of soil. In this paper, the variation of soil mechanical properties during… read more here.
