将土壤置于倾斜容器中反复进行冻融循环的实验室实验揭示了每一个凝结过程，特别是霜蠕变过程。霜蠕变的几个特征过程解释了每个循环周期中坡角对土壤表面颗粒移动量的多重影响。由于解冻后土壤中保留了过量的水分，在较厚的土层中发现了凝胶状波动。为了进一步发展这一问题，从热因素出发，导出了模型实验的相似定律。
Laboratory experiments that subjected soil to repeated freeze-thaw cycles in an inclined container revealed every process of solifluction, especially of frost creep. Multiple slope-angle effects on the amount of particle movement on the soil surface in every cycle are interpreted by several characteristic processes of frost creep. Gelifluction was found to occur in thicker layers of soil, owing to the excess water retained in soil after thawing. For further development of the problem, a similarity law for the model experiment was derived from thermal considerations.
