PREPARATORY STAGE FOR MONITORING THE LOAD-BEARING STRUCTURES OF THE OPERATED SUBWAY STATION

Academic journal Industrial Machine Building Civil Engineering, 2017
Modern technologies for the construction of a subway underground allow reconstruction of operated stations without stopping the movement of trains and subway  disruptions. However, this problem is quite complicated, because at the device of transitive tunnels it is possible to violate the stress-strain state of the main load-bearing structures and ...
