冻融作用在寒冷气候下，由于岩土中水冻结和融化等引起的若干作用的总称。包括：①冻结和融化,蒸发和凝结,升华和凝华，即岩土中水的相变；②岩土中水分、盐分和土颗粒的迁移；③土的冻胀和冻土融沉；④土的冻裂等。随着季节的交替，冻融作用会反复发生。在此过程中，细小土粒和矿物的微裂隙中的水膜的楔开压力也随着发生变化，从而导致细小土粒和矿物的破坏，使粒径变小，这种作用称为冷生水化风化。它不同于通常所说的寒冻风化。后者是由岩石大裂隙和空隙中冰的楔开压力产生的。在非冻土区，石英的最终风化粒径比长石大。但在冻土区，由于冷生水化风化，石英的最终风化粒径(0.05～ 0.01毫米)比长石的最终风化粒径（0.1～0.05毫米）为小。反复冻融时发生的另一种物理－化学作用，是胶体和粘粒凝聚成微集合体，使土的粒径增大。上述两种不同方向的作用形成一个相同的结果，使遭受反复冻融作用的岩土的粉粒含量大为增加。同时，形成一系列特殊的冷生地貌，即冰缘地貌。
