Abstract: Using random field theory, a method for analyzing variability of empirical formulas for foundation bearing capacity, such as foundation bearing capacity table and CPT, is studied. And it is pointed out that the variability of foundation bearing capacity is constituted by the variability of empirical formula oneself and variability of soil parameters. We put forward an analysis method of foundation bearing capacity variability determined by empirical formula with considering self-correlation properties of soil parameters. By the analysis and calculation of the data which workout the empirical formula, the variation coefficient is obtained, which is 0.1-0.135 .

Key words: soil parameter, self-correlation, empirical formula, cone penetration test, foundation bearing capacity, variability
