Thaw-Consolidation Behavior of Seasonally Frozen Soils

Tong Changjiang and Chen Enyuan (Lanzhou Institute of Glaciology and (ieocryoiogy.Chnese Academy of Sciences; Construction and Design Institute of Deqing Oil Field, China)  
Thaw consolidation tests were conducted on more than 1000 undisturbed seasonally frozen soil samples in laboratory. Two test methods were employed: one is loading the samples before thawing, and the other is loading the samples after completely thawed. The test results show that there is a certain difference between the total thaw consolidation settlements observed in different methods. A comparison was also made between the thaw consolidation behavior of seasonally frozen soils and that of permanently frozen soil. The comparison shows that there are some differences between the thaw consolidation behavior of seasonally and permanently frozen soil.
