Lazaryan popup.description2  The basics of determining the stress-strain state of the structure of mine shafts constructed by the New Austrian Tunneling Method (NATM) have been developed. An analysis of the stress-strain state of the combined structure of the mine shaft of the Dnipro metro was carried out. The basis for determining the stress-strain state in the lining of the escalator tunnel constructed by NATM is developed, taking into account the influence of temporary lining and options for lining the weak massif around the underground structure. The theoretical and practical determination of the stress-strain state of horizontal unfixed and fixed workings has been carried out. A comparative analysis of the results of surveying and numerical studies of the running tunnel of the Kyiv metro was carried out. Product Description popup.authors popup.nrat_date 2023-01-25 Close
