| 摘 要： | 以冰模型试验数据为参照,对数学模型进行调整和验证．在非线性有限元的分析计算中,应用了接触单元,使数学模型更接近于实际工况,获得了与试验数据相近的计算结果,并由此证明了数学模型的正确性．通过数学模型计算,分析了作用于斜面结构物上冰荷载的组成成分,深入解释了冰与斜面结构物作用的机制．模型试验与数学分析相结合,为更深入地研究以数学方法确定冰荷载作出了有益的尝试．

| Abstract: | According to the ice model test data,the mathematical model is adjusted and verified.The use of the contact element in non-liner finite element analysis makes the mathematical model more similar to the actual condition and the educed result close to the model test data,which proves the method correct.By calculating mathematical-model,the compositions of ice load on the sloping structure is analyzed with explanation of the ac- tive mechanism.Combining model test and mathematical analysis makes a useful attempt to confirm ice load with mathematical method. |
