Knowledge about the behaviour of buried flexible pipes has become more and more important in the Netherlands. It serves several objectives, for instance, to evaluate stress corrosion, installation techniques and new materials, as well as drawing up new design codes and test procedures for pipes and components. This contribution reports on the development and the application of a method to evaluate the deformation of buried flexible pipes. The results of the measurements, so far, showed the effects of laying depth, traffic load and soil type on the deformation of the pipe.
