gravitaire

CONT: Les avantages des structures gravitaires en béton sont importants et variés [...], le béton est lourd, ce qui constitue un avantage dans les structures exigeant un poids élevé [...] la structure gravitaire n'impose qu'un minimum de travail préliminaire sur le site d'installation [...]

CONT: Many [problems of steel platforms] may be overcome by the use of concrete, which also takes full advantage of the force of gravity as a stabilising influence against the lateral pressures exerted by wind and waves ... Steel platforms will have a continuing role, since seabed conditions will not always support gravity structures.
