Research on the Mechanism and Safe Thickness of Karst Tunnel-Induced Water Inrush under the Coupling Action of Blasting Load and Water Pressure

Autor: Ya Duan, Xuemin Zhang, Xianshun Zhou, Xuefeng Ou

Publikováno v: Applied Sciences, Vol 12, Iss 23, p 11891 (2022)

When the drilling and blasting method is used to construct a tunnel through the karst stratum, the coupling effect of the blasting load and the karst water pressure in front of the tunnel face exposes the tunnel face to the risk of water inrush, whic
