摘要

本文假设海冰为半无限板，海水浮力为弹性基础，海冰与极的相互作用为集中力。海冰的破裂被看作是板块的屈曲。推导了集中力作用下海板的屈曲方程，并通过数值模拟得到了临界载荷的表达式。

Critical Load between Sea Ice and Sea Structure

The following assumptions are made in this paper: sea ice is a semi-infinite plate, buoyancy of seawater is an elastic foundation and the interaction between sea ice and pole is concentrated force. The rupture of sea ice is treated as buckling of the plate. The buckling equation of a sea sheet under concentrated force was derived, and the expression of the critical load was obtained by adopting the numerical simulation.

期刊介绍： Journal of Glaciology and Geocryology (bimonthly) is an academic journal under the supervision of the Chinese Academy of Sciences (CAS), and co-sponsored by the Institute of Cold and Arid Environments and Engineering of CAS and the Chinese Geographical Society. Since its inception in 1979, the journal has focused on the study of ice, snow, permafrost and cryosphere, aiming to promote basic and applied research in related fields, facilitate academic exchanges at home and abroad, and serve the construction of national economy in cold regions. The content of the journal covers a wide range of disciplines, including glaciology, permafrost, hydrology, geo-ecology, etc., focusing on resources, environment, engineering and global change in the cryosphere. The readers are professionals in the fields of glaciology, permafrost, and hydrology, ecology and global change in the cold zone, teachers and students in colleges and universities, and leaders and cadres of governmental management departments. Journal of Glaciology and Geocryology has a wide influence in China, and is included in many famous databases and retrieval systems at home and abroad, including Peking University's ‘Chinese Core Journals List’, China Science and Technology Core Journals (CSTPCD), and Source Journals of China Science Citation Database (CSCD), etc., and has been in several journals grading catalogues The journal has been distributed to more than 20 countries. The journal has been distributed to more than 20 countries and regions, and has been indexed by international retrieval systems such as Scopus, which has a good internationalisation prospect.
