Session: Offshore and Nearshore

ABSTRACT: The transition between land and water, whether in lakes, rivers, and ocean shorelines, often presents special challenges by virtue of geological conditions as well as the geotechnical aspects relating to design, construction and operation of facilities located in such zones or activities which may take place in them. The transition zones often contain beaches which can be prominent features, particularly in areas with high tidal ranges. Structures in transition zones may include transportation facilities (such as roads, bridges, causeways, and tunnels), wharves, harbors, pipelines, power stations, sea defence and coastal management works, pumphouses and intakes, and residential areas. In terms of operations, such zones are significant from both civilian and military standpoints. Civilian activities include dredging, mining, reclamation, environmental protection, marine salvage operations, exploration, and specialized construction. From a military standpoint, such zones are obviously important in respect to amphibious landings and shoreline defense installations. The paper will review the special geotechnical issues associated with land-to-sea transition zones and ABSTRAIT La transition entre terre et eau, que ce soit dans les lacs, les rivières ou les rivages des océans, présente souvent des défis particuliers en raison des conditions géologiques et des aspects géotechniques relatifs à la conception, la ant prendre place en eux. Les zones de transition contiennent souvent des plages qui peuvent être des éléments importants, en particulier dans les zones à marée haute. Les structures dans les zones de transition peuvent comprendre des installations de transport (telles que des routes, des ponts, des chaussées et des tunnels), des quais, des ports, des pipelines, des centrales zones résidentielles. En termes d'opérations, ces zones sont importantes tant du point de vue civil que militaire. Les activités civiles comprennent le dragage, l'exploitation minière, la remise en état, la protection de l'environnement, les opérations de récupération en mer, l'exploration et la construction spécialisée. D'un point de vue militaire, ces zones sont évidemment importantes pour les atterrissages amphibies et les installations de défense du littoral. Le document passera en revue les problèmes géotechniques spéciaux associés aux zones de transition terre-mer et présentera plusieurs cas d'expérience tirés de l'expérience des auteurs et pertinents pour ces zones.
