摘要
介绍了应用模型冰进行 45°、6 0°、75°斜面墙冰作用力模拟实验装置、安装和结果 ,描述了冰排在不同倾角结构前的冰排破碎过程 ,以 45°倾角结构的水平和垂直冰力—时间曲线分析作用力过程 ,并统计了各实验的冰力特征值。利用这些实测冰力与二维理论计算冰力的比较阐明该理论模型在浅水条件下应用的可行性 ,并用水平冰力同垂直冰力比值分析碎冰堆积对冰力的影响。
This paper present the model, arrangement and results of model ice with inclined wall with angle 45°, 60° and 75°, and describes the ice sheet failure modes in front of modeled structure. One test process from 45° inclined structure is shown and mean, maximum ice forces and stand deviation from all tests are collected. From the comparison of measured ice forces and calculated ice forces, the feasibility of the theoretical model of ice force under shallow water condition was checked. The effect of broken ice pieces accumulation in front of the modeled structures on ice forces were analyzed based on the ratio of measured and calculated level and vertical ice forces, too.
