Abstract: The geological situation of Zhongshan station in the southern pole is introduced in this paper, with the frozen soil experiment completed in order to carry out smoothly the design of the tenth-five-year-plan construction of the Zhongshan Stations. The basic mechanical properties of the frozen soil in Zhongshan Station is analyzed, and the relationship between the water content and the freeze-thaw (heave) is studied, based on which the reasonable foundation scheme is put forward at the end of this paper.
