Numerical simulations of buried non-pressure polymer pipes to determine stresses and deformations are necessary for investigating their long-term behavior. Although these calculations might be straightforward, they usually face fundamental challenges in obtaining soil material data. Such data is hard to find, difficult to measure, and, if available, typically very scattered. Models using this data are subsequently hard to verify. This contribution offers a workaround by linking numerical simulations with available standards, such as the ATV German standard for designing buried polymer pipes.
