  Upheaval buckling analysis - Rapid assessment of minimum soil/rock cover required
  

  GeoLine have expertise knowlegde in performing upheaval buckling analysis and verification of online survey results. A finite element approach is used to rapid assess the amount of soil or rock required during trenching operations. The non-linear behavior of the soil uplift resistance is taken into account as well as the pipeline response due to loads within or adjacent to the imperfections.
