The development of transport requires new transport routes. When designing and implementing them, we cannot avoid the construction of tunnels in our mountainous country. One part of the static design of the tunnel is the assessment of the structure on fire. The fire of cars in road tunnels can be modeled more and more accurately thanks to improving numerical models (CFD simulations, Fire Dynamics Simulator FDS [1]) as well as an extreme increase in computer performance. The results of these investigations are appl...

A significant part of geotechnical structures such as parts of tunnels, adits, retaining walls, etc., is made of reinforced concrete. In reinforced concrete structures there are often cracks in places where they were not considered in the design. It is up to the engineer performing the fault diagnosis to determine the nature of the cracks, the cause of the occurrence and the follow-up measures to prevent their further development or eventual sanitation. The principles of conventional methods of visual diagnosis of...
