A set of simplified pipeline design methodologies are outlined for the strain analysis and design of pipelines under ground-induced actions from tectonic faults and landslides. The methodologies refer mainly to “strain demand”, as alternatives to the more elaborate finite element methodologies presented in Chap. 7. These simplified methodologies have been either developed by the authors within the GIPIPE project, or adopted from relevant publications in literature. Using those methodologies, the pipeline designer obtains a quick overview of the problem, and identifies the effects of main parameters on pipeline deformation. Comparison of the results from those methodologies with more advanced analysis tools, described in Chap. 7, shows that the simplified methodologies may provide a good level of accuracy. Therefore, they can be used quite efficiently for preliminary pipeline design purposes. The use of these simplified methodologies is illustrated using appropriate design examples. |
