Abstract
Addressing the specific scenario where the inundation zone of a newly constructed reservoir over-laps with existing gas transmission pipelines,this paper analyzes pipeline safety risks and proposes corre-sponding protective measures.Calculations carried out in accordance with relevant standards reveal that the pipelines are susceptible to floating risks,and the underwater environment will significantly accelerate the corrosion rate.The major risks posed by reservoir impoundment to the undercrossing gas transmission pipelines include uplift instability,accelerated corro-sion and difficulties in operation and maintenance.Pro-tective measures such as anti-floating weight ballast,upgraded corrosion protection,optical fiber monitoring and coordinated management are put forward.关键词
