斜面结构上冰载荷的模型试验与有限元分析

Model Test and Finite Element Analysis of Ice Load on Sloping Structure

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．

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 active mechanism. Combining model test and mathematical analysis makes a useful attempt to confirm ice load with mathematical method.
