Journal ArticleDOI
Three-dimensional numerical simulation of a mechanized twin tunnels in soft ground
TL;DR: In this article, the influence of the construction process between the two tunnels and the development of the displacement field in the surrounding ground has been analyzed using the FLAC 3D finite difference element program.
Journal ArticleDOI
2D numerical investigation of segmental tunnel lining behavior
TL;DR: In this article, a numerical study was performed to investigate the factors that affect segmental tunnel lining behavior using a two-dimensional finite difference element model, where the longitudinal joint between segments in a ring has been simulated through double node connections, with six degrees of freedom represented by six springs.
Journal ArticleDOI
Three-dimensional numerical simulation for mechanized tunnelling in soft ground: the influence of the joint pattern
TL;DR: In this paper, the authors provided a 3D numerical model of the tunnel lining behavior and the displacement field surrounding the tunnel to evaluate the influence of the lining joint pattern, including segmental lining joints and their connections.
Journal ArticleDOI
A new numerical approach to the hyperstatic reaction method for segmental tunnel linings
TL;DR: In this article, a numerical approach to the hyperstatic reaction method (HRM) for the analysis of segmental tunnel linings is proposed, which is able to consider the three-dimensional effect of segment joints in successive rings on the tunnel lining behaviour.
Journal ArticleDOI
3D numerical investigation of mechanized twin tunnels in soft ground – Influence of lagging distance between two tunnel faces
TL;DR: In this article, a 3D numerical investigation was carried out of the interaction between twin mechanized tunnels excavated in a horizontally parallel section and the critical situation in terms of the lining stability occurs when the face of the following tunnel is at the same transverse section as the preceding tunnel.
