Abstract

The pore structure and strength of loess itself will change significantly in the process of mixing organic matter, which, as the main component of solid waste at present, is of great significance for ecological vegetation restoration in loess areas. At present, the research on the internal structure and strength performance of loess through the content of organic matter is still less, this paper takes the loess mixed with different content of organic matter (0 %–6 %) and distilled water (12 %–24 %) as the object of research, and tests the electrical resistivity and pore structure of the doped organic matter loess through the LCR digital bridge test equipment and liquid nitrogen adsorption experiments. The results show that the organic matter content and water content are important factors affecting the change of resistivity of organic soil. The electrical resistivity of organic soil is correlated with its own water content and organic matter content, which is closely related to the pore type and specific surface area within the organic soil. The results of the study provide valuable references for vegetation restoration and land use and conservation strategies in ecosystems.
