ABSTRACT: In arctic area, such as on Svalbard near the North Pole, suitable good quality geological material for building protective shorelines and harbours infrastructures is often scarce. Traditional embankment solutions have short lifetime, are too expensive or do not comply with strict environmental regulations. An environmentally friendly embankment solution in arctic conditions, with geosynthetics bags and tubes filled with local soil, was developed and tested along a 100 metre coastline. Conventional and innovative monitoring systems were installed to register changes. Results after three years of installation from this embankment showed positive results to be used for a spin off project with goal to stop erosion on a quay foundation in the local harbour.

RÉSUMÉ: En zone arctique, comme au Svalbard proche du pôle Nord, les géomatériaux de bonne qualité pour construire des ouvrages de protection côtiers sont souvent rares. Les solutions traditionnelles de remblais ont une durée de vie courte, sont coûteuses et ne répondent plus aux réglementations environnementales strictes. Une solution respectueuse de l'environnement en conditions arctiques, utilisant des sacs et des tubes remplis de sol du site, a été développée et validée sur une longueur de côte de 100 mètres. Des systèmes d'auscultation conventionnels et innovants ont été installés pour mesurer les changements. Les résultats après 3 années de service sont très positifs et ont permis la réalisation d'un projet de stabilisation contre l'érosion d'un mur de quai du port local. 1 INTRODUCTION
