[ Soil Mechanics ]
I’ve kept my soil mechanics handbook from university. It’s a good reference for soil descriptions, as well as the concepts of consolidation, compaction, and permeability. Fortunately, those topics don’t change much with time.
Long-distance pipelines are mostly buried. They will be buried in soil, and will be affected by the behaviour of that soil. The ground the pipeline is buried in could be rocky, dry, or just plain mucky (a geotechnical term if I’ve ever heard one).
Sometimes specialists are needed to help with steep slopes, or hard rock. Being a pipeline engineer means knowing when that specialist is needed.
