Geosystems

Abstract

Literature on geosystems has been evaluated with the goal to come to a state of the art report with respect to the dimensioning of geosystems. Existing calculation models have been examined and compared with the results of measurements. Some extensions have been 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. This report is an extension of the report CO-369280/43 of November 1997. The influence of air and the degree of filling of the geocontainer is 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.KWP-collectio
