study that focused on the likely vibration levels that may be expected in drilling and blasting the tunnel. The field work conducted at three sites along the proposed tunnel line involved the firing of 46 individual charges below the ground and had masses between approximately . Highlights The effect of new tunnel blast excavation on adjacent existing ones was studied. A PPV-based damage control method is proposed for tunnel blast excavation. The rock damage extent linearly increases with the PPVs on the existing tunnel wall. No failure will occur in the tunnel linings if the PPV is less than m/s. The surrounding rock damage can be controlled by blast vibration Cited by:

Structure response and damage produced by ground vibration from surface mine blastingAuthor. Unknown. This book seeks to provide an introduction to tunnel construction for people who have little experience of the subject. Tunnelling is an exciting subject and is unlike any other form of construction, as the ground surrounding the tunnel is an integral part of the final structure and plays a pivotal role in its stability.
