Research, monitoring and control at different stages of underground structures created by the urbanized territories
The main methods of research, monitoring and control are given at different stages of the lifecycle of the underground structure created within the urbanized area. The first stage of the lifecycle of the underground structure is considered, characterized by survey at the design stage, which is the basis for the formation of geological subbase of the area of underground construction. The characteristics of the geological environment scrutiny for cities is given. A list of the most common methods is represented used to solve these problems at the stage of engineering and geological surveys based on the complexity of engineering-geological conditions. Targets of research, control and monitoring at the various stages of the lifecycle of the underground facilities are systematized. The direct and indirect physical and technical methods for monitoring the stress-strain state of the rock mass, selected on the basis of the monitoring tasks are considered. The conclusions are made that for constructions built under difficult engineering-geological conditions it is advisable the creation of full-scale stationary systems of geocontrol using modern means of collection, processing, storage, transmission and display of information.
