Abstract
The knowledge of the spatial variability of geotechnical parameters, which can be described statistically by the mean, the variance, and the scale of fluctuation, is important in reliability-Based design. of particular importance is the scale of fluctuation. It can be used to compute the variance reduction factor, a factor of spatial averaging of geotechnical properties to reduce their point variance. the most prevalent method of determining the scale of fluctuation uses datasets whose data points are at close and regular intervals, e.g. measurements from cone penetrometer soundings. Another method, when continuous measurements are not available, uses datasets that are widely spaced and at irregular intervals. Presented in this paper is a comparison of the range of influence of the undrained shear strengths at three different locations in Missouri determined from continuous and regularly spaced CPTu data and the non-continuous and irregularly spaced Shelby tube sampling data. © 2011 ASCE.
