Damage criteria of Burland and Boscardin & Cording. Examples of mitigation measures.

Specific Objectives

Learn how to roughly assess the damage that the excavation of a tunnel can cause to the structures close to its alignment. Familiarize with damage mitigation measures that can be applied to limit the consequences of damage as much as possible.
