In this paper, the rock mass stability around the tunnels in an underground mine is
investigated using the distinct element method. A three-dimensional model was developed …

To investigate the mechanism of tunnel supports for large squeezing deformation hazards,
the explicit cohesive element-based numerical manifold method (ECo-NMM) is extended …

The presence of karst cavities near the tunnels has a great impact on the behavior and
deformation of the tunnels, making it necessary to study the impact of these cavities before …

The back analysis method is widely used in geotechnical and geological engineering to
guide construction and assure safety through feedback analysis and dynamic design. In this …

The 3D laser scanning technology is implemented to multi-temporally scan the lining of a
NATM tunnel during construction. An improved moving average method (IMAM) is firstly …

Abstract Tunnel Boring Machine (TBM) penetration rate prediction is one of the most
important problem in tunneling projects. Estimating of Tunnel Boring Machine (TBM) …

Ground squeezing induced by tunnel excavation is a common phenomenon in weak and
jointed rock masses. The prediction of convergence during tunnel construction in squeezing …

Due to the complexities of design and technical issues of construction, tunnels are
considered to be enormous financial investments. Therefore, rehabilitation with the purpose …

Due to ignoring the role of real topography in the numerical modeling carried out for back
analysis and considering that in the tunnel longitudinal profile the distance of tunnel roof to …

This paper presents the application of the observability technique for the structural system
identification of 2D models. Unlike previous applications of this method, unknown variables …
