Abstract: Thawing settlement deformation is one of the main freezing damage for the structure in permafrost region. The actual thawing settlement is the superposition of two parts: thaw settlement and compression settlement. The volume compression coefficient is the key calculation parameter in estimating the compression deformation. Basing on the 286 thawing compression test data of undisturbed frozen soil samples, it has put forward various types of regression equations including linear equation, binomial equation and logarithmic equation and these equations represent the relationship of volume compressibility and dry density of six sorts of soil on the two different pressure sections 0−100 kPa and 0−200 kPa. These soil types are fine gravel, sand, silt, clay, peaty clay and peat. On this basis the empirical volume compression data table of the six sorts of soils is given out; meanwhile, the problems in recommended methods of specifications are pointed out.

Key words: thawing settlement coefficient, volume compression coefficient, dry density
