Abstract: In order to reveal the mesoscopic deformation mechanism of loess high-fill
foundation of Luliang airport, the soil electrical resistivity-consolidation combination measuring
instrument are developed based on the principle of soil electrical resistivity. The dynamic
variation law of the electrical resistivity of Q3 loess are obtained through in-situ monitoring, field
sampling and laboratory test under different initial saturations and constant load. The electrical
resistivity-strain curve model of Q3 loess to the limits of optimum moisture content is proposed;
and its moisture migration and structural changing characteristics under constant load are also
obtained. The study results show that the post-construction deformation of the loess high-fill
foundation top surface is composed of the consolidation deformation of initial foundation and
the fill bellow the surface to a certain depth and the long-term creep deformation of deep
overconsolidated soil. The mesoscopic deformation mechanism of soil is revealed initially; and
the study provides scientific basis for the establishment of loess high-fill soil constitutive model
and reasonable selection of the numerical analysis model.
