Abstract:

The research for dynamic properties of frozen soil is the development of statics, and it is the important basis of analyzing dynamic instability. The research status for mechanical properties of frozen soil at home and abroad is summarized. Static properties of frozen soil are mostly researched, dynamic properties of frozen soil focus on the low frequency or small amplitude vibration tests. According to the magnitude of strain rate, the dynamic mechanical properties of frozen soil are researched by adopting split Hopkinson pressure bar test under high strain rate. It is an important research for the safe, effective and rapid construction in frozen construction of coal mine and artificially frozen engineering, and it is of great significance both in research and application.

Key words: artificial frozen soil, dynamic properties, engineering application, impact loading
