Damage distribution along pipe subjected to rate-dependent ground movements with significant axial components

Buried pipeline systems form a key part of effective and safe infrastructures for the transportation of natural resources such as natural gas and liquid. However, they may be constructed in areas prone to landslides where ground movement may exert excessive strains on the pipe sections causing rupture. This project develops and presents a methodology for estimating strains in a pipe under axial loading induced by ground movement. The procedure calibrated and validated with pipe movement survey data and advanced computer modelling is based on a simplified analytical approach that can be readily implemented in practical design and analysis. A series of design charts are generated for performance evaluation of buried pipeline systems constructed in active slopes. They can be used to assess the frequency of necessary remediation such as in-situ stress relief procedure to protect the environment and maintain pipeline integrity and operation.
