【 摘 要 】

The experience of construction of marine hydraulic structures in severe hydrometeorological operating conditions on the coast of the Far Eastern seas has been considered. The characteristic failures of concrete in a zone of variable level after first wintertime have been analyzed. The reasons of an evident sudden failure of concrete are detected. A scheme of concrete structure forming under the impact of frost and salt depending on the "structural maturity" of concrete is proposed. The lines of further researches on forecasting of longevity of concrete and reinforced concrete facilities for maritime hydraulic structures have been evolved.
