METHOD OF PRODUCING TUNNEL LINING IN ANISOTROPIC ROCK

摘要

FIELD OF THE INVENTION The invention relates to hydraulic engineering. The purpose of the invention is to increase reliability in operation by reducing filtration losses. After drilling the grouting wells, a group of wells located in a row along tunnel 1 in the direction of the maximum modulus of rock deformation is charged with space-borne explosives. Charges are set at a depth beyond the decompression zone 16 of anisotropic rock 2. An explosion is produced, and then a cement slurry is injected. 2 Il.
