Prevention of Large Deformation of Soft Surrounding Rock in Tunnel Construction

open access: yesJournal of Measurements in Engineering, 2023
Large deformation of surrounding rock makes the internal space of a tunnel cannot meet the requirements of normal use after support, even leads to the instability of surrounding rock and destruction of the tunnel structure. In order to optimize the parameters of the primary support to control the deformation of surrounding rock, field tests and ...
