Seismic Analysis of Delhi Metro Underground Tunnels

Indian Geotechnical Journal, 2016
Metro underground tunnels are strategic elements in transportation and utility networks in any metropolitan city and their importance makes their vulnerability to earthquakes a very sensitive issue. A large earthquake would not only cause loss of human lives but can also damage lot of other pertinent infrastructure.

Tunnelling the Cairo metro line no. 2

Tunnelling and Underground Space Technology, 1992
Abstract The need to build a metro network consisting of three main lines—a regional line and two urban lines—was the outcome of a transportation study carried out between 1970 and 1974 for Greater Cairo City. A 4.5-km-long underground line was constructed under the city's central business district (C.B.D.) to connect two existing railway lines ...

What Does a Metro Tunnel Look like?

2018
A metro tunnel is the section tunnel between two adjacent stations. It is a super long and linear structure connected by the lining ring extending in the longitudinal direction. The lining ring is assembled with the shield segments. The shield segment is a reinforced concrete structure, whose steel bar is like the bone of a human being and concrete is ...

Energy Tunnel Experimental Site in Turin Metro

2017
Energy geo-structures such as piles, diaphragm walls, tunnel linings and anchors are rapidly spreading in Europe and all around the world. They differ from traditional geotechnical infrastructures because they are equipped with absorber pipes. The working fluid circulating in the pipes extracts or injects heat into the ground depending on the season in
