Typology of metro structures for the tasks of geotechnical risk classification

Risk management is an important part of a modern enterprise activity. Currently, risk management should be included in the overall quality management system of a construction organization. Geotechnical construction, for instance, construction of metro, should also be carried out taking into account possible risks. Metro construction is connected with a number of uncertainties related to enclosing rock mass conditions, and specific geotechnical risks, which can lead to materialization of hazards with various consequences. Predicting possible hazards at all stages of a metro structure life cycle requires the ability to manage risks. The effectiveness of risk management requires detailed risk identification, which precedes the stage of determining the probability of risk (the risk assessment stage). To identify an object, it is required to determine its composition, properties, physical origin. The method of such risk cognition with division into groups through determining the essential features (grounds) is classification. To date, different classifications of risks in construction activity have been developed. The paper discusses various approaches to the classification of risks in underground construction, analyzes the feasibility of adapting these classifications to the analysis of geotechnical risks in the construction of metro facilities. The principles of classification of geotechnical risks were proposed. The typology of metro structures has been substantiated as the basis for the classification of geotechnical risks in the construction of metro facilities. The results of the development of a general form for classification of geotechnical risks during a metro construction have been presented.
