Abstract

The influence of nonlinear wave structures on the local hardness of an ice field of a dynamic type of formation is studied. Wave structures are formed by the interference of flexural–gravitational and longitudinal waves. The source of oscillations is coherent radiation in the ice itself. The difference in the local hardness of ice in the nodes and antinodes of standing waves (up to 60%) is explained by the dynamic metamorphism of ice. The dependences of the local ice hardness on the coordinates in the longitudinal and transverse profiles of the ice field have the form of periodic curves. The texture scales were determined, and the phase surface of the wave structures was constructed, which is not monochrome and reflects the spatial heterogeneity of the strength properties of the ice field. The effect of the wave action depends on the conditions at the interface between the ice and the pool walls. The influence of wave structures on the strength properties of the ice field as one of the possible factors of the spatial variability of ice under various modes of occurrence in situ is quantified.

平稳周期波结构对冰场局部强度的影响

摘要

研究了非线性波结构对动力型地层冰场局部硬度的影响。波浪结构是由挠曲引力和纵波的干涉形成的。振荡的来源是冰自身中的相干辐射。冰的动态变质解释了驻波波节和波腹中冰的局部硬度差异（高达60％）。局部冰硬度对冰场的纵向和横向轮廓上的坐标的依赖性具有周期曲线的形式。确定了纹理尺度，并构造了波浪结构的相表面，该相结构不是单色的，反映了冰场强度特性的空间异质性。波浪作用的效果取决于冰和水池壁之间界面处的条件。定量分析了波浪结构对冰原强度特性的影响，而冰原强度特性是在各种原位发生模式下冰层空间变异性的可能因素之一。
