Estimation of Optimal Spacing between CPT Soundings
The cone penetration test (CPT) has become one of the preferred methods of site characterization, particularly for large infrastructure projects, partly due to its simplicity and partly as a result of the development of reliable cone resistance-based correlations for footing design, pile design, and liquefaction resistance estimation. This paper presents a statistical methodology for estimation of optimal spacing between CPT soundings performed at a site in a way that is logical and easy to implement in geotechnical practice. The methodology quantifies the variability of a site in the horizontal direction through a horizontal variability index, which is a function of the spacing between soundings, the cross-correlation of cone resistances, and the difference in cone resistance trends between all pairs of soundings within the test site. The methodology is illustrated using CPT data obtained from multiple soundings performed at a bridge construction site in Lafayette, IN.
