冻胀引起的地表变形已经引起了近一个世纪的实验室、现场和理论研究。早在能够分辨支持液体向生长的冰透镜输送的微观薄膜的设备发展之前，早期的研究人员就预测到了它们的发生，并注意到了它们的重要性。理想化的实验继续推动理论的进步，这些理论已经结合在一起，开发出了在现场看到的宏观冻胀特性的预测模型。这一贡献突出了我们目前对控制冰如何在松散多孔介质中形成的物理相互作用的理解的步骤。
Abstract The deformation of the ground surface that is produced by frost heave has motivated almost a century of concerted laboratory, field and theoretical studies. Well before the development of equipment capable of resolving the microscopic films that support liquid transport towards growing ice lenses, early investigators predicted their occurrence and noted their importance. Idealized experiments continue to prompt theoretical advances that have been combined to develop predictive models for the macroscopic frost-heave characteristics that are seen in the field. This contribution highlights steps on the road to our current understanding of the physical interactions that control how ice forms in unconsolidated porous media.
