| 摘 要： | 随着在海冰区海洋工程结构物的增多,对海冰力学性质的研究引起了注意。1985-1987年在渤海进行了海冰物理力学性质的初步研究,进行了6个方面的测试。测试内容有海冰的单轴抗压强度,弯曲强度,剪切强度,冰晶体结构,冰温度、冰盐度、冰密度、弹性模量,泊松比和海冰的断裂韧度。海冰的强度与海冰温度有密切关系。冰温度降低,冰强度增加,通过测量海冰盐度和它的强度发现海冰盐度越高,冰强度越低。海冰强度与加载速度有关系,加载速度直接影响海冰强度。

| Abstract: | This paper presents some results of recent studies on the sea ice physics and mechanics of Bohai Gulf, including uniaxial unconfined compressive strength, flexural strength, modulus of elasticity, friction coefficient, density of the ice, air temperature, water temperature, unixial tensile strength, shear strength, crystal structure, brine volume, temperature of the ice, and ice salinity. These datum are measured in the northern part of Liaodong Bay from January 1985 to January 1987. |
