In many geotechnical applications like pile installation processes or soil improvement large deformations of the surrounding soil occur. These large deformations in combination with the complex material behaviour of the soil lead to numerical boundary value problems which are often difficult to solve. These difficulties are related to large mesh distortions and numerical problems due to complex contact conditions. One possibility to overcome these difficulties is to use special numerical techniques which are especially invented for large deformation simulations. In this work, the Coupled Eulerian-Lagrangian method (CEL) is identified to be well suited for such boundary value problems involving large distortions of the surrounding soil. Therefore, the numerical technique is presented and its suitability is shown in different geotechnical applications. The screwed pile installation and the deep vibration compaction process are investigated using the CEL method. © 2013 Taylor & Francis Group, London.
