Pipeline Integrity Management Under Geohazard Conditions (PIMG)
Chapter 11 AN OVERVIEW OF CURRENT METHODS FOR MONITORING LANDSLIDE GROUND MOVEMENT TO BETTER UNDERSTAND POTENTIAL HAZARDS TO BURIED PIPELINES
Download citation file:
Landslide-related ground movement may occur rapidly and without warning or may occur slowly over time. Both rates of movement, if engaging a buried pipeline, may result in increasing adverse strains to, and possible failure of the pipeline. To effectively manage both the near-term and long-term threat associated with landslide-related movement on pipeline systems, it is important to first identify and characterize the landslide threat, and then develop a mitigation and monitoring program to manage the risk associated with the threat. A landslide threat monitoring program, if tailored correctly for a given pipeline system, can be used to identify newly-developing...
