【摘要】 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.更多还原

【Abstract】 A series of shear strength tests on freshwater ice were conducted in Hongqi-pao reservoir.The total shear strength data of 236 samples were achieved.The change rule of shear strength were analyzed with the temperature,shear strain rate and loading direction.The change rule of shear strength with shear strain rate were obtained by the test results,the test relationship between the peak shear strength with ice temperature was concluded using statistical analysis.According to the anisotropy of reservoir ice,the difference of the shear strength were analyzed under different loading direction.更多还原
