Research on the Blasting Shock Absorption Technology of Shallow-Buried Tunnel Under-Traversing the Dense Houses
How to deal with a conflict between blasting vibration damage of tunnels construction with complex shallow and the efficiency has been always a difficult technical problem. Relying on the Chang Hong Ling tunnel which under-traverses the Jiangchi Town, using of field monitoring method to comparative study on the blasting vibration under different blasting scheme construction, research shows that: the up-step of non-blasting excavation + lower-bench of controlled blasting technique, successfully controls the surface blasting vibration speed within 1.5 cm/s.Then the tunnel can be constructed safely and rapidly, which provides a reference for the blasting excavation engineering in urban.
