作用于正倒锥结构上冰力物理模拟试验研究

利用新型非冻结可碎合成模型冰材料，进行了冰排对正倒锥体结构物作用的物理模型试验研究；试验中测量了作用于锥体结构物上的冰力，并观察记录了冰排作用于结构物的破坏过程。综合分析试验结果，发现冰速的变化对冰力没影响。而随锥角、水线直径的增加以及冰排弯曲断裂模式由下弯变为上弯，作用于锥体结构物的冰力显著增加。试验得到的总冰力结果与Croasdale和Ralston的理论预测结果符合较好。

Study of physical simulation experiment for ice force on combined cone

Physical model tests are conducted for the investigation of iceforces acting on the structure with combined cone by using the new non-frozen breakable synthetic materials. The total ice forces are measured and the flexural failure processes of model ice sheets are recorded. The results of the measured ice forces agree well with the predicted results of Croasdale′s and Ralston′s theoretical models. It can be seen from the test that the variance of ice velocity has no influence on the ice forces and with the increasing of the cone angle, waterline diameter and the change of the breaking modes from downward breaking to upward breaking, the ice forces increase obviously.
