Abstract

This paper investigates the data obtained from field tests and laboratory geotechnical experiments. Based on the semi-variogram method theory and the establishment of a random field model foundation, the data is detrended, followed by verifying stationarity and ergodicity. We comparatively analyze three models using the semi-variogram method to calculate fluctuation ranges and determine spatial variation coefficients. Finally, the covariance matrix decomposition method is employed to construct the random field model, thereby achieving spatial variability analysis of soil parameters in thick loess-filled strata. The main conclusions are: (1) The spherical model demonstrates the highest probability (80%) among optimal mathematical models, suggesting priority consideration for fluctuation range calculations. (2) Variation coefficient analysis reveals medium variability in compression modulus, weak variability in shear wave velocity, cohesion, natural density, and internal friction angle. (3) The covariance matrix decomposition method proves most appropriate for establishing this random field.
