Based on the characteristics of ice failure against conical structure and model test results,an ice force time history is developed ,which is applied to a caisson structure to determine its dynamic responses by the use of forced vibration theory. Two models of linear and non-linear simulation technique are adopted to consider the horizontal stiffness of pile foundation. The calculation results show that the structure will vibrate under certain ice condition ,but the magnitude of vibration is less, not enough to influence the structural strength and personnl working efficiency. The dynamic response of linear simulation is greater than that of non-linear simulation ,so the dynamic response could be determined based on equivalent linear foundation stiffness.

本文根据锥体上冰层破坏特点及模型试验结果构造了作用于基础结构上的冰力时程曲线,按强迫振动理论计算了某沉箱结构的冰激动力响应。对桩基础的水平向刚度模拟采用了等效线性及非线性两种模式。计算结果表明,在一些特定冰层作用下,结构有可能发生振动,但振动量值不大,不致影响结构强度及人员的工作效率。按线性基础计算的动力响应大于非线性基础的响应,因此采用等效线性基础刚度计算动力响应是可行的。
