| 摘 要： | 该文通过淡水冰的系列单轴抗压试验研究,探讨了加载速率、冰试件尺寸、试件横截面形状以及加载接触面对冰强度和压应力-应变关系的影响;试验研究和理论分析表明：在高径比小于2时,相同截面尺寸冰试件的抗压强度随构件高度的增加而提高,当高径比大于2时,强度变化不明显;随着截面尺寸加大,相同高径比试件强度稍有下降,即具有一定的尺寸效...

| Abstract: | In this paper,a series of uniaxial compressive tests of ice were carried out,and the effects on ice compressive strength and stress-strain relationship of loading rate,specimen dimensions,section shapes and loading contact-face were investigated.Based on the above tests and analyses,the following conclusions were drawn: when the height-diameter ratio of specimen is smaller than two,the compressive strength of ice increases with the increase of height,and keeps almost constant when the height-diameter ratio ... |
