Abstract EN
Based on the characteristics of long annual freezing time and short suitable construction period of soft soil in cold region, this paper discusses the feasibility of foundation treatment of soft soil in freezing-thawing layer under freezing condition.
the deformation characteristics of soft soil in freezing-thawing layer in hulunbuir area in China are studied by using two compression test methods, namely, constant temperature and variable load (CTVL) test, variable temperature and variable load (VTVL) test.
the compressibility indexes under different temperatures and consolidation pressures are obtained.
the research shows that the freezing-thawing soft soil has large compressibility, the maximum strain of CTVL test is 19.89%, and the maximum compression of VTVL test can reach 18.16%.
The results of CTVL compression tests show that when the soil temperature is in the range of severe phase change (-1.5℃-0℃), the temperature change has the greatest influence on the compression coefficient of soil.
the result of VTVL compression test shows that some additional deformation occurs under the action of low temperature.
the additional deformation is further increased when the soil is under high consolidation pressure and in the severe phase change (-1.5℃-0℃).
