Physical simulation of ice forces on hydraulic structures——Ⅱ.DUT-1 Model Ice physical and mechanical properties

介绍DUT-1模型冰的物理指标(密度)、力学指标(弯曲强度、弹性模量、压缩强度、摩擦系数)的试验方法和主要特征。特别给出控制模型冰物理和力学参数的水泥含量和养生时间的试验规律和统计关系。通过试验结果也证实在模型冰密度和弯曲强度、弹性模量和压缩强度之间存在内在联系,这些联系也存在良好的试验统计关系。

The experimental methods and main features of DUT-1 Model Ice physical parameter（density） and mechanical parameters（flexural strength,elstic modulus,compressive strength,friction coefficients） are introduced.Especially,the experimental behavior and statistical relations of model ice physcial and mechanical prameters with concret contents and curing times are given.From the results of the series tests,the internal links between model ice flexural strength,elstic modulus,compressive strength and wetted density are found and the best experimental relations are statisticized.
