| Description: | CRREL Report From the Introduction: When moist fine-grained soil freezes, it often is accompanied by volume expansion caused by the appearance of layers of more or less pure segregated ice within the soil. The scientific investigation of segregated ice began in the early 1900s, but the understanding gained by Taber (1929, 1930), Beskow (1935) and others, although useful, was largely qualitative. Since then a significant amount of effort has been made to gain a quantitative understanding on ice segregation. We will consider the one-directional steady growth of an ice layer. Let the freezing process advance from the top down and the coordinate x be positive upwards with its origin fixed at some point in the unfrozen part of the soil. A transitional zone, often referred to as the frozen fringe, exists between the frost front (0°C isotherm) and the growing surface of an ice layer, though the nature of this zone has not been well understood. A freezing soil in this problem may be considered to consist of three parts: the unfrozen part R o, the frozen fringe R 1 and the ice layer R2, as shown in Figure 1. |
