São Paulo Metro – developments in shield tunnelling
Geomechanics and Tunnelling, 2014AbstractThe Metro Network in São Paulo has five lines in service with a total length of 107 km in one of the most booming cities in South America with a population of over 11 million inhabitants. The network can still be considered to be in its early stages; the first line was only constructed in 1968 and is now being extended.

Design of the metro tunnel project tunnel linings for fire testing
Structural Concrete, 2020AbstractWith a growing pipeline of major transport infrastructure projects transforming Victoria's road and rail networks, there is an increase in demand for the construction of underground tunnels using the shield tunneling method. Such tunnels need to be designed for fire resistance in order to preserve both structural integrity and serviceability in

After the inspection report of the major distress in tunnel is done, the consultation will be held among the experts to determine the current service condition and what’s wrong with the tunnel through comparing the distress with the quantitative evaluation criteria and referring to the comprehensive condition evaluation system. The service condition of

Athens Metro Line 3: Complex Tunnel Geometries
Geotechnical and Geological Engineering, 2014Complex tunnel geometries are very common during the design of urban tunnelling and especially metro lines. Relevant complexities were common during the construction of Athens Metro in Greece, where the need of giving access to trumpet areas, multi-storey underground constructions and transition zones produces special design requirements ...

Impact hammer applications in Istanbul metro tunnels
Tunnelling and Underground Space Technology, 2008Abstract Hydraulic impact hammers have been used widely in Istanbul metro tunnels since 1992. This paper summarizes recent studies and explains the basic principles of the proper selection of hydraulic impact hammers. First data on 600 different hydraulic impact hammers available in the market are analyzed and the relationships between operational ...

Experts’ Diagnoses for Metro Tunnel
2018In traditional Chinese medicine (TCM), the doctor can tell the diagnosis after using the four diagnostic methods including observing, listening, asking, and feeling the pulse of the patient. Now the question is how can one judge and tell that if the tunnel structure is in an ill condition or not?
