The Colombian petroleum pipelines go through different types of geomorphologies and geological settings; so that the pipeline system is exposed to a variety of processes such as landslides, erosion, scour, sedimentation, and karstification. In order to prevent some of the effects caused by these processes, geotechnical remedial works have been designed and implemented over time. However, in some cases the remedial actions have not exhibited a proper behavior. For this reason, a better understanding of local conditions is required in order to conceive more effective solutions.
This paper provides an overview of a methodological framework for geotechnical assessment and design of mitigation measures based on the evaluation of geological and geomorphological aspects, computational tools, and data processing. Finally, the characteristics of an existing and unsuccessful mitigation civil work are described, and a brief summary of the relevant geotechnical aspects of the proposed design are presented.
