Design of Foundations on Layered Soil

The Challenge of Foundations on Layered Soils One of the major challenges for all geotechnical engineers when considering foundations on layered soil,  is that “design codes” don’t provide closed form solutions for calculating the bearing capacity. The design methods specified in such codes are typically for drained or undrained conditions including linearly increasing strength gradient …

Pipeline Geotechnics: Flow Assurance

Flow Assurance For typical oil and gas pipelines, the fluid transported will be a mixture of hydrocarbon gases and liquids that will remain stable within a given pressure and temperature regime. For the purposes of our fictitious pipeline, we shall consider an inlet temperature of 100 degree Celsius and a well-head flowing pressure of 350 …
