Subway construction in the central parts of cities requires the implementation of the latest technological advances in underground construction. These achievements relate to the construction of the main road arteries of the metro. Despite the implemented technical innovations in mass construction, problems need to be solved that require a creative approach for unique cases in technology and security. Risk cases along the subway route are most often concentrated in areas in contact with existing facilities and cont...

For the most risky sections in the metro construction, the postulates of the mining methods using steel structures have to be used. With the classic settings of these methods, innovative technical solutions can be achieved, to which this report is dedicated. It is necessary to search for simplified, safe and durable tunnels and shafts when crossing existing subway lines. On this basis, the statements of the specific geomechanical tasks were formulated. In the case of shafts, the fundamental differences in the appl...
