对红旗泡水库淡水冰开展了剪切强度系列试验,累计得到236个试样的剪切强度数据.分析了剪切强度随温度、剪切应变速率以及加载方向的变化规律.通过试验结果得到剪切强度随剪切应变速率的变化规律,利用统计分析得出峰值剪切强度与冰温度的试验关系.同时分析了水库冰各向异性特点,产生不同加载方向下剪切强度的差异.
A series of shear strength tests were carried out on the freshwater ice in Hongqiuba Reservoir, and the shear strength data of 236 samples were obtained.Changes of shear strength with temperature, shear strain rate and loading direction were analyzed.Through the test results, The relationship between shear strength and ice temperature was obtained by statistical analysis.Analyzing the anisotropy of reservoir ice and the difference of shear strength under different loading directions,
