Abstract

Acoustic and electrical properties determined for frozen saline soils (sand and silt) of massive cryogenic structure with different water contents (three values for each type of soil), salinities (seven values for silt and five for sand) and temperatures (–2, –4, and –6°C) are presented in the paper. A good correlation between the specific electrical resistivity and the concentration of the pore solution and between the ratio of the concentration of the pore solution to the temperature and the velocity of longitudinal waves was obtained. The electrical resistivity of the low saline soil was 2–22 times higher than that of the highly saline soils, while the longitudinal wave velocities only differ by factor of two. Therefore, the electrical properties are the most suitable parameter for ranking soils by their salinity.

盐度对冻土声电特性的影响

摘要

针对具有不同水分含量(每种类型的土壤为三个值),盐度(七个粉土值为五个,沙子为五个)和温度(–2,–本文介绍了4和–6°C)。在比电阻率与孔溶液的浓度之间以及孔溶液的浓度与温度的比率与纵波速度之间具有良好的相关性。低盐度土壤的电阻率是高盐度土壤的2-22倍,而纵向波速仅相差2倍。因此,电学性质是最适合根据土壤盐度分级的参数。
