| Abstract: | Frost heaving mounds of hollow-domelike frost blister type and candle ice type were found in this area. The former can be divided into 5 layers, namely, surface humus soil, domelike massive ice, empty dome loose debris as well as permafrost layer with particulate ice , and the latter can be divided into 4 layers, namely, surface humus soil, candle ice, massive ice and permafrost layer with particulate ice. It is found from the investigation that both of them are seasonal frost heaving mounds. Based on analyses of forming mechanism, the authors consider that transmission of cold wave in winter,. hydrostatic pressure of closed system freezing suprapermafrost ground water, shallow and low permeable layer, as well as fine soil material of ground surface are the prerequisite for developing seasonal frost heaving mounds in the region. |
