Study on the influence of blasting on the structural stability of newly-built and adjacent tunnels.

With the rapid development of urban underground spaces, newly constructed tunnels are being constructed increasingly closer to existing ones. In such cases, blasting may cause overbreak and underbreak, potentially compromising both the structural stability of the new tunnels and the operational safety of adjacent tunnels. In this study, we investigated the double-track tunnel project in Chongqing University Town; the blasting operation was classified into the blasting action period (from the beginning to load termination of blasting) and the overbreak period (from blasting termination to surrounding rock deformation stability).

Study on the influence of peripheral eye on over-excavation during mountain tunnel blasting construction.
