It continues by stating that a robust design is one where the risk of failure or damage to the tunnel works or to a third party from all reasonably foreseeable causes, including...

This paper sets out a framework for forensic geotechnical assessments of foundation failures, involving...

The work included statistical analysis of hydrological data dating back to 1827, from which it was shown the 2002 event had a considerably long return period. However, the investigation also revealed...

Identifying causes of failure and the party responsible, plus technical presentation of subsequent...

It is vital to learn from all failures, and grouping them under interfaces offers a convenient categorisation.
