Geodetic Monitoring of Large-Span Underground Facilities During Construction of the Rogun Hydroelectric Power Station

Resumo

Problems related to the creation and functional operation of a system of geodetic monitoring of large-span underground facilities at the Rogun hydroelectric power station are considered as functions of the engineering geology conditions of occurrence of the rock. Results of long-term regime geodetic measurements are presented. The process of activation and the significant scatter of the degree of convergence of the walls of the machine hall chamber in the siltstone and sandstone zones are identified.
