Determination of water content of saline soil with multielectrode resistivity method

Saline soil contains more soluble salt. Its engineering properties to moisture content are very sensitive. In combination with laboratory data and field test, this paper explores the resistivity method to indirectly measure the feasibility of saline soil moisture content. Saline soil water immersion test area of effect was surveyed with multielectrode resistivity under specific temperature of indoors. Relationship of resistivity of saline soil and moisture content was determined. Combining with the results of multielectrode resistivity inversion profile, the field observation of soil temperature field test is calculated within the scope of the water immersion test influence of the moisture content. Comparing with the moisture content of stratified sampling, the reliability of the mathematic models is verified.
