Which risk to unanchored pipeline integrity increases significantly when infrastructure crosses regions exhibiting solifluction?

💡 Explanation

When pipelines cross solifluction zones, slow downslope movement of saturated soil causes cyclic stress because frozen ground thaws, creating unstable flow, leading to fatigue. Therefore cyclic stress is the main risk, rather than corrosion, cathodic demand, or embrittlement which depend on electrochemistry or material properties.
