PLAXIS

The first article describes an evaluation of suction anchor bearing capacity with the 3DFoundation program. In general, 3D models are not as accurate as 2D models. As a result, ultimate limit states (such as safety factors or bearing capacities) may be overestimated.
The second article involves the stability analysis of slurry wall trenches. The situation is during construction is clearly three-dimensional. In addition to safety factor analysis, the authors describe a probabilistic design method.
In the third article a 3D analysis of a complex offshore foundation is described. Instability of the seabed is an important issue here. Gravel banks were proposed to stabilize the foundation. In the calculation different loading situations were considered.
