Design of Anti-Blasting and Wave-Elimination Protection Layer in Surrounding Rock of Cavern Based on Computer Simulation Technology

Abstract

Based on the computer numerical simulation software ANSYS and AUTODYN, this paper describes the construction concept and implementation method of a new type of anti-blasting and wave-elimination layer in the surrounding rock of cavern. Through the numerical simulation method, the wave-elimination effect of the hole group layer in the surrounding rock is analyzed, and the attenuation ratio of the hole group to the peak stress of explosion wave is quantified. This paper studies the wave-elimination effect of the crack zone of wave protection layer in surrounding rock and gives its construction technology. It is recommended to use computer numerical simulation technology to study and optimize the subsequent surrounding rock stability and fracture zone structure, so that the new wave-elimination protection technology can be applied in practical engineering as soon as possible.
