Abstract
Disclosed are a method and a device for identifying full-section excavation parameters of large-section tunnel with broken surrounding rock, capable of solving the problem of inaccurate arrangement of blasting hole points in tunnel excavation engineering, and including the following steps: establishing a three-dimensional finite element model based on a blasting section design of a tunnel; performing a simulation with the three-dimensional finite element model based on blasting design parameters to obtain blasting quality parameters; selecting a group closest to a preset quality parameter from multiple groups of the blasting design parameters as target blasting design parameters, wherein the preset quality parameter is an acceptance grade standard of the tunnel; obtaining first thermal imaging information of a first hot spot of a surface to be blasted; calibrating actual hole spacing parameters based on the first thermal imaging information and the target blasting design parameters.
