- 摘要:
- 通过海冰与人工岛护坡结构相互作用的理论分析,对辽东湾某人工岛护坡结构抗冰稳定性进行了计算,并对影响抗冰稳定性计算的相关参数进行了分析,结果表明,1 t扭王字块体和2 t扭王字块体均满足海冰作用下的稳定性要求,300 kg护面块石不能满足海冰作用下的稳定性要求;现有关于海冰与斜坡式人工岛护坡结构的计算方法偏于保守,有待于改进。
By means of theoretically analyzing the interaction of sea ice and revetment structure of artificial island, the ice resistance stability of revetment structure of the artificial island in Liaodong Bay was calculated, and some related parameters which could affect ice resistance stability calculation were analyzed. Results showed that 1 t and 2 t accropodes could meet the stability requirement under the action of sea ice, but 300 kg armor stones could not; existing computing method about the interaction of sea ice and revetment structure of artificial island would tend to be conservative and should be improved.2012,1(1): 24-26 收稿日期：2011-11-28DOI：10.3969/j.issn.1001-2206.2012.01.007作者简介：穆剑(1960- ),男,北京人,高级工程师,1982年毕业于中国地质大学(武汉)地质专业,2002年毕业于中国地质大学(北京)地质专业,博士,现从事石油勘探与生产管理工作.参考文献：
