| 摘 要： | 通过对作用在锥体结构上的各种静冰力预测模型的介绍,根据大量实验室模拟测试数据,运用直方图对比、无量纲效应分析及统计分析等手段,对有关静冰力计算公式进行了全面分析与确认.所采用的分析方法为我国渤海辽东湾JZ20-2平台原型冰荷载测试数据与预测模型的比较,为利用原型观测数据建立适合于我国渤海环境条件下冰对锥体结构作用力预测模型,提供了有效的技术手段,同时也为有冰海域结构物的可靠性分析提供了各统计量有价值的参考数据.

| Abstract: | Some prediction models that can be used to predict sheet ice forces acting on conical structures are in-troduced. An assessment is made to compare several representative prediction models with experimental messure-ments for sheet ice forces on conical structures. Differences among the models are identified. Statistic measurements of these models are provided so that the uncertainty of accuracy for each of the models can be quantified. This method can be used for comparison in-situ observatica on platform JZ20 - 2 with the prediction models, and the statistic results are necessary for the analysis of the structure reliability. |
