Management and Monitoring of Urban Environment in the Integrated Development of Underground Space

Abstract

The paper presents the results of developing the system of managing and monitoring the urban environment in the integrated development of the underground space. Its main elements are a block of geotechnical management and monitoring, a block of energy management and monitoring of life support systems, a block of ecological and socio-economic monitoring. The essentials and principles of construction of each block are considered. The key attention is paid to geotechnical monitoring in the construction of underground structures with the use of protective screens. The features of stress distribution in the span tubes and the side walls of the protective screen are established based on the analysis of monitoring data. By means of numerical simulation by the finite element method, the stresses in the span pipes and vertical deformations of the soil mass are obtained over the span from the rigidity of the pipe section area. An improved design of a protective screen with the possibility of regulating its vertical resistance by means of hydraulic jacks is proposed. The effectiveness of this technology in the development of underground space is determined not only by economic, but also by social and environmental aspects.
