A model of the thermo-elastic behaviour of saline ice is formulated, and model solutions describing thermo-elastic waves (TEW) propagating into a half-space of the ice are investigated. The model is based on a proposal that saline ice is a matrix, which encompasses both closed brine pockets and permeable channels filled with brine. Experiments on the thermal expansion of saline ice samples, and on TEW in saline ice, have been performed in the cold laboratories of the University Centre in Svalbard and in University College London. The experimental data are compared with theoretical conclusions. The experimental data support our hypothesis that the brine in saline ice is divided between closed pockets and open, permeable channels.This article is part of the themed issue 'Microdynamics of ice'.
建立了盐冰热弹性行为模型,并研究了描述热弹性波(TEW)传播到冰半空间的模型解。该模型基于这样一种假设:盐冰是一种基质,它包含封闭的盐水囊和充满盐水的渗透通道。在斯瓦尔巴大学中心和伦敦大学学院的低温实验室中,对盐冰样本的热膨胀以及盐冰中的热弹性波进行了实验。将实验数据与理论结论进行了比较。实验数据支持了我们的假设,即盐冰中的盐水分布在封闭的囊和开放的渗透通道之间。本文是“冰的微观动力学”主题特刊的一部分。
