摘要
本文叙述的是一个多项目的野外试验,该试验主要测试了渤海湾海冰和黄河口河冰的压缩、剪切和弯曲强度。此外,还测量了冰的温度、盐度、密度。文中叙述了冰的现场试验方法及得出的试验结果。同时还讨论了冰的各种强度值与冰温、应变速率(或应力率)的关系,且冰的强度是冰温和应变速率的函数。冰是各向异构体,加载方向不同,呈现的强度值也不相同。并且还对比了海冰与河冰的异同。
In the paper, some of field tests of sea ice are presented. In the tests, compre-ssive strength,shear strength and flexural strength of sea-ice in the Bohai Bay and in the Yellow River mouth have been measured.In addition to this, the measurement of temperature,salinity and density of ice has also been carried out.The test methods and test results are given. Then the relation of ice different strength values with ice temperature and strain rate (or stress rate) is discussed. Besides, ice strength is a function of ice temperature and strain rate. Ice is a heterogeneous crystal.Therefore, in different loading directions the strength value is different, Sea ice is also compared with the river ice in the mechanical properties.
