| 摘 要： | 为了满足窄锥结构动冰力函数构造的需要，提出了一个新的锥体结构冰力计算公式，公式由体现锥角效应、接触宽度效应和冰断裂长度效应三参数表达，它能够合理地反映冰力幅值与作用周期的相关关系。算例结果与几个有影响力的经验公式和理论公式的比较显示，新公式能更好地模拟结构的实际冰力。

| Abstract: | A new formula used for the ice force analysis of the narrow conical structures is presented, with which the requirements for the constructing of dynamic ice force function are satisfied. The new formula is expressed with three parameters with which the effects of the angle and the diameter of the conical structure and the broken length of the ice sheet are considered. The interaction between the extent and the period of ice force is expressed. Calculation results of the example show that the new formula may simulate the actual ice forces more reasonably than the empirical formulas and theoretical formulas, which are influential in the world. |
