Abstract

Abstract

Based on the thermal conductivity coefficients of soil skeletons obtained by experiments and the microscopic mechanism of interaction between soil particles and pore water, the influence of the pore water content on thermal conductivity coefficients of frozen soil was analyzed. With the increase of the pore water content, the two characteristic points would appear in the curve of soil thermal conductivity coefficients, they were called "the soil structure control point" and "the soil structure dispersion point" respectively. The curve of thermal conductivity coefficients could be divided into three phases by the two varible characteristics points:1) the combination phase of soil skeletons and strong binding water; 2) the phase of water-filled pores of soil; 3) the phase of soil skeletons damaged by pore water. On the basis, the change laws of soil thermal conductivity in these three stages were studied by using the physical model of heat transfer, and the simple and practical formula of thermal conductivity coefficients was obtained based on the theory of the electric lattice model.
- water content,
- thermal conductivity coefficient,
- frozen soil,
