摘要
为了寻求测试冻土水理参数的低冰点液体,以东北季节性冻土区为参考区,在探究冻结土壤水理性质中,选择出一种适合用于冻结土壤基本参数测定的低冰点液体,测定出含水率为20%的冻土渗透系数,研究冻土的水理性质,同时测定含水率为20%的非冻土渗透系数,探究冻土与非冻土水理性质的差异。研究内容以寒区低温条件为主要特色。
This study takes the Northeast seasonal frozen soil areas as the reference area. In the process of researching the frozen soil water and soil properties,a low freezing point liquid suitable for the determination of the basic parameters of the soil is selected,the permeability coefficient of frozen soil with the moisture content of 20% is measured,and the hydro logical properties of frozen soil is studied.Simultaneously,the permeability coefficient of non-frozen soil with the moisture content of 20% is measured,and the difference of water property between frozen soil and non-frozen soil is explored. The low temperature in cold area is the feature of this study,and seeking a low-freezing liquid for the parameters test of the frozen soil is the innovative point.
