Anti-explosion and reinforcement effects on a cavern with a new prestressed anchor cable
Vibroengineering Procedia, 2022 Traditional cavity reinforcement technology is difficult to effectively protect the cavity from damage caused by modern large-yield explosions, and the anti-explosion performance of prestressed anchor cables needs to be improved urgently. The design of a new prestressed high-elastic fully adhesive anchor cable for the enhancement of the anti-explosion ...
