The ability to detect early signs of failure in buried pipe infrastructure is necessary facilitate the continued use ageing for delivery society’s essential services and move beyond disruptive expensive reactive maintenance repair. This paper reports detailed experiments on in-pipe ultrasound techniques assessment ground conditions around plastic pipes. Two sets ultrasonic experiment soil are p...

Understanding soil-pipe interaction during cyclic axial displacement is essential for the design and evaluation of buried pipeline systems. This study introduces an efficient practical numerical approach using beam-spring-interface elements to simulate behaviour. Numerical predictions evolution shear normal stress distributions around pipe are validated against full-scale experimental results s...

The goal of cathodic protection is to prevent corrosion by maintaining buried pipelines at a constant potential with respect to the surrounding soil. In practice, however, the implementation is very complicated since many factors can contribute to the current flowing off the pipe. Design requires characterization of the parameters impacting the corrosion process, such as soil resistivity, size ...
