Evaluation of loosened zones on excavation of a large underground rock cavern and application of observational construction techniques
AbstractTo ensure the stability of caverns and optimize the support systems, observational design and construction procedures have been used recently for excavating large underground caverns, such as those for pumped-storage power plants, which spontaneously process data monitored during construction and real-time feedback of the results to the next construction steps. In observational design and construction procedures, the cavern support systems should be optimized by monitoring the loosening behavior and correctly predicting and analyzing the subsequent behavior of the cavern. This paper describes an evaluation of loosened zones based on monitored stress of rock and an application of prediction analysis for observational construction techniques.
