Objectives
The objectives of this work package (WP1) are the following:

• Critical assessment of existing know-how for strain-design of buried steel pipelines against geotechnical hazards, through consideration of appropriate pipeline design examples.
• Compilation (data base development) of existing data / field experiences from geotechnical hazards and their evaluation based on the consequences of the structural performance of pipelines; identification of critical modes of failure
• Evaluation of analytical/numerical models simulating mechanical behaviour of soil-pipeline systems under ground-induced permanent actions.
