Model Experiment Study on Anti-Explosion Characteristics of Underground Caverns Reinforced by External Cross-Anchoring

“…As anchor reinforcement technology was widely used in underground engineering, research institutions at home and abroad have conducted some test to research anchor the antiknock performance and dynamic response of bolt [1,2], the linear relationship between PPV value on the top of the anchor with the peak of dynamic load [3], antiknock function of spray layer and anchor, responses in different segments of tunnel under blast loading etc. All of them were based on the same prerequisites sufficient coating layer.…”
