DESIGN CONSIDERATIONS FOR COASTAL PROJECTS IN COLD REGIONS

摘要

Design considerations for coastal projects in cold regions include not only the oceanographic factors that tend to assume primary importance in temperate climates, but also ice and thermal factors. This paper reviews the current understanding of each of these three types of design considerations, with emphasis on the lessons learned from recent project experience in the Alaskan Beaufort Sea. It is concluded that the environmental influences unique to cold regions introduce both increased complexities and increased uncertainties into the design process for coastal structures. In consequence, a conservative approach that incorporates damagetolerant components and non-catastrophic failure modes is recommended for the design of sensitive facilities.
