Study of Construction Methods for Large Undersea Concrete Structures.

摘要

The study was undertaken to annotate up-to-date capability of the construction industry to emplace those structures on the seabed. In equating this capability to the requirement,several methods and combinations of systems were evident,predicated on the final site selection for the emplacement. Each offshore site has a different set of geographical conditions that should be evaluated prior to designing and selecting any one method for construction. The report considers these variables in water depths up to 1000feet deep. In evaluating design and construction methods for even larger objects and at depths up to 3000feet,additional unknowns were indicated by the research. From this research and analysis several future study areas were suggested. Concepts involving underwater mixing and placing of concrete were reviewed along with various justifications for such developments. Recommendations and items for future research are also included in the report. (Author)
