Results from Two Geotechnical Benchmark Problems
One of the aims of the working group 1.6 “Numerical Methods in Geotechnics” of the German Society for Geotechnics is to provide recommendations for numerical analyses in geotechnical engineering. In addition benchmark examples are specified and the results obtained by various users employing different software are compared. So far two simple examples, namely a tunnel excavation and a deep excavation problem, have been set up and results have been discussed at a workshop. This paper summarizes the most important aspects of this exercise. It shows that despite the simplicity of the examples and the rather strict specifications significant differences in the results are obtained even in cases where the same software has been utilized by different users.
