Abstract: When tunnels are constructed at shallow depths in areas with poor geological conditions, such as portal sections, valleys and hillsides in regions with granitic bedrock, considerable excavation-induced deformation of the surrounding rock may occur, potentially… read more here.

DOI: 10.1016/j.ijheatmasstransfer.2016.09.010
Abstract: Abstract Permafrost is very sensitive to temperature changes. Climate warming would cause the increase of ground temperature and accelerate the degradation of permafrost. One of the important future issues is how to control ground temperature… read more here.

DOI: 10.12989/gae.2017.12.2.313
Abstract: Based on the reliability theory and limit analysis method, the roof stability of a shallow tunnel is investigated under the condition of surface settlement. Nonlinear Hoek-Brown failure criterion is adopted in the present analysis. With… read more here.
