Risk control system for the construction of urban underground structures

Abstract

Complex development of dense urban underground space puts forward a number of requirements that must be taken into account when planning, designing and building, because underground structures under construction and in operation are high-risk areas and, in the event of an accident, pose a serious danger to the people in them. The purpose of the risk control system for the construction and operation of underground structures in megacities is to ensure the successful functioning of urban systems in conditions of risk and uncertainty. In the event of an emergency, the implementation of risk control measures should ensure that the adverse impact caused by accidental events on the successful operation of megacity facilities is minimized. The article considers the functional risk control system in urban underground construction, presents an analysis and classification of risk-forming factors that affect the environmental and technological safety of urban underground space development. Qualitative and quantitative indicators of risk development were identified. The main requirements and principles of forming a risk control system for the development of urban underground space are formulated.
