| 1 | 渤海海冰孔隙率对单轴压缩强度影响的实验研究显示文摘针对2009~2010年冬季渤海出现的异常冰情,在辽东湾东岸某港区外潮沟采集海冰,加工成冰样;在控温精度0.1℃的条件下,对117个柱状冰冰样沿平行冰面方向加载,测试冰样的单轴压缩强度、密度、盐度.试验温度分别是?4℃,?7℃,?10℃,?13℃和?16℃,加载应变速率在10?6~10?2s?1,覆盖了冰的韧性破坏、韧脆过渡和脆性破坏区域.试验结果支持宽应变率范围内单轴压缩强度随孔隙率的变化曲面.由此得到冰力学行为转折点随孔隙率变化的定量表达;实现了描述单轴压缩强度在不同破坏行为下的统一数学表达式;此外,还推断出2009~2010年渤海异常冰情不会导致渤海海冰单轴压缩强度设计值的调整. | 李志军 张丽敏 卢鹏 Matti LEPPARANTA 李广伟 | 2011 | 中国科学:技术科学2011，41，10： | 21 |
| 2 | Experimental study on the effect of porosity on the uniaxial compressive strength of sea ice in Bohai Sea显示文摘For the abnormal ice condition in 2009–2010 winter,sea ice samples were collected in a tide ditch outside a port in the east coast of Liaodong Bay,and ice specimens were prepared.Experimental study was carried out with a temperature-control precision of 0.1°C,and 117 columnar-grained ice specimens were loaded along the direction parallel to ice surface under different test temperatures(-4,-7,-10,-13,-16°C)and strain rates ranging from 10-6 to 10-2 s-1 within which the ductile region,ductile-brittle transition and brittle region are contained.The uniaxial compressive strengths,density and salinity of the ice specimens were measured.The results support the curved-surface relationship between the uniaxial compressive strength and porosity within a wide range of strain rate.The curved-surface relationship gives a quantitative description about the variations of the mechanical behavior transition point with ice porosity,and supplies a uniform mathematical representation of uniaxial compressive strength under different failure modes.Besides,it is deduced that abnormal ice condition in 2009–2010 winter will not result in a change of the uniaxial compressive strength of sea ice in Bohai Sea. | LI ZhiJun ZHANG LiMin LU Peng Matti LEPPARANTA LI GuangWei | 2011 | Science China(Technological Sciences)2011，54，9： | 12 |
| 3 | Distributions of crystals and gas bubbles in reservoir ice during growth period显示文摘In order to understand the dominant factors of the physical properties of ice in ice thermodynamics and mechanics,in-situ observations of ice growth and decay processes were carried out.Two samplings were conducted in the fast and steady ice growth stages.Ice pieces were used to observe ice crystals and gas bubbles in ice,and to measure the ice density.Vertical profiles of the type and size of ice crystals,shape and size of gas bubbles,and gas bubble content,as well as the ice density,were obtained.The results show that the upper layer of the ice pieces is granular ice and the lower layer is columnar ice;the average crystal size increases with the ice depth and remains steady in the fast and steady ice growth stages;the shape of gas bubbles in the upper layer of ice pieces is spherical with higher total content,and the shape in the middle and lower layers is cylinder with lower total content;the gas bubble size and content vary with the ice growth stage;and the ice density decreases with the increase of the gas bubble content. | Zhi-jun LI Wen-feng HUANG Qing JIA Matti LEPPARANTA | 2011 | Water Science and Engineering2011，4，2： | 5 |
