Fewer research studies, however, have been performed on a 3D numerical simulation of the interaction mechanism between mechanized twin tunnels and groundwater (Zheng et al., 2015, Losacco and Viggiani, 2019). To summarize, the literature reviewed above demonstrates that numerous studies have been conducted on the interaction of twin tunnels.

01/05/2014 · It is well known that the interaction between mechanized twin tunnels excavated in soft ground is complex. In this study, a 3D numerical model of the mechanized twin tunnelling process has been developed. This model can be used to predict the ground movements and structural forces induced in the lining of two tunnels excavated in parallel.

The increase in transportation in large cities has made it necessary to construct twin tunnels at shallow depths. As far as the parallel excavation of mechanized twin tunnels is concerned, most of the cases reported in previous studies have focused on the interactions between two horizontally driven tunnels. However, less work has been devoted to the interactions between tunnels stacked over ...

A 3D numerical model of the mechanized twin stacked tunnelling process was developed in this study. The excavation of a new tunnel was shown to have an important impact on both the behaviour of the linings installed in the existing tunnel and the displacements of the ground surrounding the twin stacked tunnels.

Most of the reported cases in the literature on parallel mechanized excavation of twin tunnels have focused on the effects of the ground condition, tunnel size, tunnel depth, surface loads, and relative position between the two tunnels on tunnel behaviour. The numerical investigation performed in this study, using the FLAC 3D finite difference element programme, has made it possible to include the …
