中文摘要：
为了研究作用在自升式平台结构带齿条桩腿上的冰力，进行了一系列模型实验来对比两侧带齿条的圆柱压头和不带齿条的光滑圆柱压头上的冰力。实验结果表明：当齿条尺寸相对圆柱直径较小时，自升式压头上的最大挤压冰力与圆柱压头上的最大挤压冰力差别不大，且齿条方向与冰板运动方向夹角的改变，对自升式压头上的最大挤压冰力无显著影响。根据对模型实验结果的分析，提出自升式平台带齿条桩腿上挤压最大冰力的计算方法，并指出了自升式平台上存在的3种挤压冰力模式。
英文摘要：
In order to study ice forces acting on the legs with toothed bars in the jack-up platform, a series of model tests were conducted to compare ice forces on two smooth cylindrical indenters of the same diameter.One that actu-ally have a toothed bar on both sides and the other one has no toothed bar.The results of the model tests indicated that when the size of the toothed bar is smaller compared with the diameter of cylinder, the maximum ice crushing force acting on the jack-up indenter is slightly different from the maximum ice crushing force acting on the cylinder indenter.In addition, the change of the included angle between the ice moving direction and the direction of toothed bar does not apparently affect the maximum ice crushing force acting on the jack-up indenter.Based on the model test results and subsequent analysis, a method for calculating the maximum ice crushing force on legs is proposed and three kinds of existing ice crushing modes are pointed out.
