[en] The most commonly used model in The Netherlands to predict settlements is the Koppejan Model. This model gives reasonable predictions, but sometimes there are large discrepancies with reality. This is caused (among others) by: 1) The inaccurate calculation of the degree of consolidation, 2) The omission of the consolidation process for creep, which causes superposition errors for (temporarily) surcharge calculations, and 3) The omission of the waterpressures caused by creep. The problems disappear when the settlement process is solved with an incremental calculation. The results of the incremental calculations are compared with several 1-D compression tests and show good results. The Incremental Koppejan Model can easily be implemented in finite element models. In this paper also an example for a 3-D Elasto-Plastic Soft-Soil-Creep Model is presented.
