GEOTEXTILE-REINFORCED RETAINING STRUCTURES: A FEW INSTRUMENTED EXAMPLES ---PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM ON THEORY AND PRACTICE OF EARTH REINFORCEMENT, FUKUOKA, KYUSHU, JAPAN, 5-7 OCTOBER 1988

Based on a few examples of instrumented real structures, this paper emphasizes the influence, on the behaviour of polymeric reinforced structures, of various parameters such as: (a) the method of placement, of both the formwork and the facing; and (b) the possible use of clayey soil. The structures studied were: the La houpette embankment; an embankment on the a7 motorway; the langres structure on highway 19; the luchon inflatable formwork structure; and the rouen experimental retaining wall which made use of clayey soil. The conclusion to be drawn from these few instrumented examples is that the tensile forces, and in particular, their distribution in the structure, depend to a large extent on the conditions of placement, but also on the way structure is stressed. In addition, an attempt should be made to optimize the mobilization of the forces by choosing a type of form that allows pretensioning of the geotextile and holds deferred deformations of the structure to a minimum. For the covering abstract of the symposium see IRRD 818063.
