"frozen soil" is correct and usable in written English.
You could use it in a variety of contexts relating to cold temperatures, including scientific writing, fiction, and nonfiction. For example, "The temperature dropped below -10C and the soil became frozen."
The FTC-time analogy method can be used to solve problems of forecasting long-term frozen soil strength, as well as for research concerning frozen soil engineering.
To illustrate the soil frost dynamics over time, the measured liquid water content of frozen soil (LWCFS) was transformed into different expressions including frozen soil profile, frost penetration map, freezing front trace and thawing front trace.
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.
Permafrost, which is a layer of permanently frozen soil found in northern climates, houses thousands of years of organic matter.
When liquid contaminants entered the voids of partially ice saturated frozen soil, the rate of ice erosion was significantly increased.
It is also found that seasonally frozen soil may impact bridge seismic behavior; the lateral displacement capacity of the pier decreases and the shear demand increases in the frozen soil condition.
Compared with unfrozen soils, frozen soil has the most important characteristic under natural conditions its matrix, which is composed of ice and water, changes continuously with varying temperature, which implies the mechanical properties of frozen soil are dependent on temperature.
The higher temperatures are causing the subsurface layer of permanently frozen soil typically found in the Arctic to thaw in some areas.
In the second experiment, a frozen soil was prepared by freezing a mixture of smectite mineral and water.
Other than these advantages of frozen soil, the volume increase of freezing water leads to an undesired frost heave.
They won't survive frozen soil.
