%K Permafrost;hydrothermal parameters;China Russia crude oil pipeline
%X This dataset contains soil water and thermal parameters data from four typical sites along the China Russia crude oil pipeline (MDS8, MDS94, MDS166, MDS283). The relevant parameters are obtained based on indoor standard tests conducted after on-site sampling, which can truly reflect the basic physical properties and thermodynamic characteristics of permafrost soil under the background of pipeline engineering disturbance. The data content includes key indicators such as soil moisture content, density, specific gravity, organic matter content, liquid and plastic limits, thaw settlement coefficient, freezing temperature, and thermal conductivity.  This dataset can provide basic parameter support for the study of soil freeze-thaw process, water heat force coupling response, and thaw settlement deformation under the action of buried pipelines in permafrost regions for many years. It can also serve as important input data for numerical simulation, permafrost stability evaluation, and secondary freeze-thaw disaster risk analysis. It has important application value for the safety assessment and prevention measures optimization of permafrost engineering.  The data elements are as follows:  Moisture content (W):%, reflecting the moisture content in the soil.  Density (ρ): g/cm ³, representing the mass per unit volume of soil, reflecting the compactness and bearing capacity of the soil.  Specific gravity (Gs): dimensionless, the ratio of the mass of soil particles to the mass of accumulated water, reflecting the physical properties of soil particles.  Organic matter content (Wu):%, reflecting the proportion of organic components in the soil, affecting the structural stability, water retention, and thermal physical properties of the soil.  Liquid limit (WL):%, the water content limit of soil in a flowing state, characterizing the plasticity and range of soil plasticity.  Plastic limit (WP):%, the water content limit at which soil transitions from a plastic state to a semi-solid
