Interlayer oxidized zone and argillite-sisandstone-argillite sequence occur in red clastic rock formation with ideal artesian and circulating system of ground water.
Thermokarst failures occur when permafrost—a layer of frozen soil in Earth's polar regions—thaws and becomes unstable, possibly releasing greenhouse gases into the atmosphere.
Based on the quality data of overyear water table and groundwater, the research studied the dynamic variation of water table and quality of groundwater.
The resistance to float relates to the attributes and conditions of the ground water, the pressure and floatage of water, the change of water level and the sudden supplement of water.
