摘要
新建的中国船舶科学研究中心小型冰水池采用淡盐水溶液制成了柱状模型冰。为了评估该模型冰的物理力学性能,进行了一系列试验测量。其中,利用取自冰层的大量样本对模型冰单轴压缩强度特性进行了检测分析,观察了模型冰的破坏模式和断裂行为,研究了压缩强度对应变率的依赖性。在对试验结果进行综合分析和评价的基础上,提出了进一步改进模型冰单轴压缩强度研究的方向。
A series of measurements were carried out in the newly-built small ice model basin(SIMB)of China Ship Scientific Research Center(CSSRC)in order to assess the physical and mechanical properties of the model columnar saline ice made from a thin sodium chloride solution,among them the characteristics of uniaxial compression strength were determined with a number of samples from ice sheets.The failure mode and the fracture behavior of the model ice as well as the dependency of the uniaxial compression strengths on the strain rate were investigated.The direction for further promoting such a study on uniaxial compression strength of model ice is outlined based on comprehensive analysis and evaluation of the testing results.
