While pipeline materials are generally ductile and thus resistant to elevated strains, US Department of Transportation (DOT) statistics suggest that between 1991 and 2000, around 30 pipeline failures were attributed to natural forces. Natural forces are defined in general causal categories including subsidence, landslide, mudslide, frost heave and washout. To enhance pipeline safety and serviceability through better understanding of geotechnical hazards, BMT with Pipeline Research Council International (PRCI), the US DOT and pipeline operating company support, has developed an advanced pipe-soil interaction design and assessment support tool to provide guidance on the pipe deformations and stress states generated due...
