The use of an underground transportation network to solve urban traffic problems is a
practical solution. Shiraz, one of the most famous touristic cities of Iran, is developing its own …

This paper presents an assessment of the influence of the lagging distance between two
horizontal tunnel faces of the side-by-side twin tunnels on the responses of the adjacent …

Mechanized tunneling method using Tunnel Boring Machine (TBM) is being extensively
employed in urban areas, especially when excavation takes place underneath the …

Tunnels may be constructed in a pair undercrossing existing geotechnical structures
exposed to cyclic loading. Such construction changes the stress state in the ground in …

Three-dimensional numerical analyses were developed to study the interaction between
twin tunnels and underground parking in an urban area. The mechanized tunneling …

In order to solve connectivity problems in metropolitan areas, the development of
underground metro lines constitutes an unquestionable requirement. However, the …

The complexity and variability of the structural distribution and combination characteristics of
jointed rock masses make the response mechanism of tunnel rock collapse different, and …

The transportation system is one of the major infrastructures in urban areas, and it serves
56% of the world's population. Nowadays, metro lines are developing fast in urban areas …

In recent decades, numerical calculations have often been used to optimise, from a technical
and economical perspective, the design of underground works. Using these tools allows …

The performance of segmental linings in China's Yellow River Crossing Tunnel is studied as
a case study, and a complete three-dimensional numerical model is developed for the …
