Abstract:

Taking the case of frozen soil in Fuxin city of Liaoning province,the frozen-heave factor of ten kinds of frozen soil have been experimentally studied under the condition of analogizing groundwater level. The test results indicate: there is a obvious effects of anti-freezing for the frozen soil in Fuxin city of Liaoning province when replacement layer is above the groundwater level about 30 cm,the largest deep-freeze for 62 % and the thickness of the deep freeze 30 %.

Key words: frozen soil, replacement zone, depth, thickness, groundwater level
