FOUNDATIONS FOR STRUCTURES IN SOFT SOILS USING THE REINFORCED EARTH TECHNIQUE

CIMENTACION DE UNA ESTRUCTURA EN SUELOS BLANDOS USAN DO LA TECNICA DE LA TIERRA ARMADA

A description is made of the experience gained in designing and constructing the Bilbao-Behovia Motorway laid on soft soils. The foundation question was in fact solved by direct foundations, despite the problems that arose over stability and settling, by applying the technique of reinforced earth to solve the problems of abutments. The interest of this article lies in the data it supplies on the possibilities provided by using the reinforced-earth technique as a means of solving, with economic advantages, the problem of foundations for structures under particularly difficult conditions and with limitations in the construction times allowed. The main problem arose over settlement of the scaffolding and forming for the concrete slab from the time of the concrete pouring to the first prestressing, 7 days later, which gave rise to cracks in the bottom face of the slab which disappeared with the second prestressing. The total settlement suffered by the structure, of somewhat more than one metre, has demonstrated the real strain capacity of the reinforced earth which has stood up well to the differential settlements of up to two per cent per linear metre which, to the authors' knowledge, are the highest figures recorded up to the present in published geotechnical literature on similar structures. /TRRL/
