Geosystems

Literature on geosystems was evaluated with the goal to come to a state-of-the-art report with respect to the dimensioning of geosystems. Existing calculation models were examined and compared with the results of measurements. Some extensions were made on existing models to calculate the stresses in the geotextile of a geocontainer during impact and to improve the model of Higuchi. Dimensioning of a geocontainer is still difficult since the knowledge of the critical loading during opening and impact is still limited, resulting in inaccurate models, whereas experiments present inconclusive results. Some upperbound approximations for design are presented. The influence of air and the degree of filling of the geocontainer are investigated, as well as the stability and the influence of stones in the bottom under the geocontainer on the loading of the geotextile. Furthermore, the experiments performed by ACZ on geocontainers have been evaluated.
