| 摘 要： | 南水北调西线区域处于高原连续片状冻土区向高山不连续岛状冻土区过渡的中间地带。区域内多年片状冻土、岛状冻土和季节性冻土三种类型并存,造成了冻土分布的复杂性与多变性。依据大量实际资料,系统论述了区域内冻土、地下冰、融区的分布与特征,冻胀与融沉的各种现象。

| Abstract: | The region of west line of transferring water from the south to the north is locatedin the intermidiate belt of the plateau continuous sheet permafrost and the high mountain eiscon-tinuous island permafrost. The coexistence of three kinds of frost earth, i. e., the sheet per-mafrost, island permafrost and seasonal frost earth,have led to the complexity and changeabilityof the frost earth distribution in this region. On the basis of a lot of concrete data the authors havedecribed systemically the distribution and features offrost. earth,groundice and melted region,andalso various phenomena of frost heaving and thaw settlement. |
