| 摘 要： | 通过冰力模型试验,研究了锥体冰力的特征。试验得到的正锥体冰力大都小于美国API荐用Ralston公式计算的冰力,Ralston公式未反映冰速对冰力的影响;多锥体前冰的非同时破坏现象以及锥间距对冰力计算具有不同程度的影响;冰在正、倒锥体交界线上的破坏为挤压破坏,其冰力远小于作用在同直径桩柱上的冰力。 |
| 关 键 词： | 冰力 模型试验 锥体 冰非同时破坏 正、倒锥体交界线 |

| Abstract: | In this paper, the characteristics of ice force on conical structure has been studied by model tests. The test data of ice force on upward bending cone are mostly greater compared with the results calculated by Ralston formula recommended by American API, because Ralston formula does not consider the effect of ice velocity on the ice force. The non-simultaneous failure of ice on double-cone structure and the space between cones influences the calculation of ice force. The ice failure mode on the interface of upward and downward bending cones has been proved to be crushing and the ice force acted on the interface is much less than that acted on the pile with same diameters. |
