Studying the shape of geotextile tube
Yassine AMALLAS, Youssef AJDOR
Abstract
Geotextile tubes are severally more and more used in maritime field as systems of beaches protection against coastal erosion. The predicting of their dimensions is very important, because these dimensions govern the stability against several site conditions of wave and current. There are many studies to calculate dimensions of geotextile tubes, but they require the running of a computer program and this limit their access to large public designers. The most popular is the approach presented by Leshchinsky et al. (1996) in the program GeoCoPS 2.0 In this paper, a new numerical approach was established to calculate dimensions of geotextile tubes regarding the degree of filling FA (%). The results were presented in a computer program. The approach developed is based on same relationship used by Leshchinsky and other authors and iterations of all parameters. At the conclusion of this paper formulas, depending only on FA (%), to calculate dimensions of filled geotextile tube are proposed.
