摘要：

Freeze-thaw hazard is one of the main problems in cold regions engineering and artificial ground freezing engineering. To mitigate freeze-thaw hazards, it is essential to investigate the effects of freeze-thaw on soils engineering properties. This paper summarizes the effects of freeze-thaw on the physical and mechanical properties of soils reported in recent studies. The differences of freeze-thaw conditions between freezing shaft sinking and cold regions engineering are discussed. Based on the technological characteristics of freezing shaft sinking in deep alluvium, we further attempt to identify key research needs regarding the freeze-thaw effects on the engineering properties of deep soils.
