An analytical model of loosening earth pressure in front of tunnel face for deep-buried shield tunnels in sand

Computers and Geotechnics, 2019
Abstract For deep-buried shield tunnels in sand, it is difficult to determine the loosening earth pressure in front of tunnel face due to the significant soil arching effect during excavation. Considering the soil arching effect and the correlation between the relative displacement of soil and the arching deformation patterns, this paper proposed a ...

The Effect of Model Scope on Numerical Results for Deep-Buried Tunnel

Tunneling and Underground Construction, 2014
The numerical simulation method has become one of the most important assistant approaches for engineering design. But for the model scope of the overlying strata of deep-buried tunnel, there's no consensus which could be accepted by the whole geotechnical engineering industry; and, in most cases, the boundary of the model is determined by experience ...
