摘　　要：为探究冬季已冻结的河流湖泊在不同冰厚下的冰层可否进行冰上活动,利用Ansys Workbench有限元软件和Winkler弹性地基模型进行模拟计算,对其承载力进行预估,并绘制冰厚与冰层承载力图,与国内外不同理论和经验公式进行比对,验证其方法的可靠性。结果显示,此方法可以预估冰层在低风险范围内的承载力,所得结果对冬季冰上活动和进一步确定不同冰厚下的冰层承载力具有一定的实际应用价值。To explore the feasibility of ice activities on rivers and lakes that have already frozen in winter under different ice thicknesses,this paper uses Ansys Workbench finite element software and the Winkler elastic foundation model for simulation and calculation to estimate the bearing capacity of the ice layer.A graph of ice thickness versus bearing capacity is plotted,and the results are compared with various domestic and international theoretical and empirical formulas to verify the reliability of the method.The results show that this approach can predict the bearing capacity of the ice layer within lowrisk ranges.The findings have practical application value for winter ice activities and further determination of the ice layer bearing capacity under different ice thicknesses.
