Risk management by geotechnical monitoring for safe excavation of a large rock cavern: a case study

T Bhatkar, A Mandal, C Kumar, A Usmani - Bulletin of Engineering …, 2017 - Springer
The present report highlights the methods used to monitor the rock mass behavior and
performance of a cavern during excavation in order to verify and, if necessary, adjust the
rock support to ensure safe construction at each stage of excavation. The present
geotechnical monitoring practice for underground structures involves convergence
monitoring with the help of optical targets and rock mass displacement with the help of
borehole extensometers. More importantly, it involves detailed planning to finalize the …
