Scientific concept and application of frozen soil engineering system

Abstract Frozen soil is “cryalfs” in soil classification and belongs to a “special” soil type category in engineering geology and geotechnical engineering. Based on the system theory of engineering geology, we used scientific philosophy to describe frozen soil engineering as a whole research system. The frozen soil engineering system is such a complex synthesis that it is difficult to define the complete physical process in this system. According to the dynamic change between atmosphere, engineering construction and frozen soil, this study breaks up the frozen soil engineering system into two circles: the atmospheric engineering circle and the engineering frozen soil circle. Moreover, the mutual connection, interdependence, interaction and mutual restrict of many elements involved in the frozen soil system were expound. Frozen soil engineering system is a functional collection of interactions between natural and artificial objects in permafrost regions, which as a scientific logic methodology is established in order to solve frozen soil engineering problem. It has high effectiveness, more economy, more application, and low maintenance when applied in engineering construction in permafrost regions, and it will be more realistic and safer.
