Description of the Spatial Variation of Compositional and Mechanical Soil Parameters is Often Paramount in Site Characterization of Geotechnical Design and Analysis. the Values of the Parameters Themselves Largely Depend on In-Situ State Factors Which Are Related to Spatial Locations. Also, for Large-Scale Engineering Projects Such as Earth Dams or Highways, It is Generally Expected that Heterogeneous Site Characteristics Will Be Revealed by Investigations at Spatially Distant Locations. Currently, Most Reliability-Based Design Methods Are based on the Second-Moment Statistics (Mean and Variance). However, They Are Unable to Adequately Describe the Spatial Variation of Soil Properties. in This Paper, Spatial Correlation …

A Soil Variability Analysis is Presented in This Paper. About 317 Unconsolidated Undrained Triaxial Compression Tests (UU) Were Carried Out on Undisturbed Samples from Four Locations in Missouri. the Spatial Variation of the Undrained Shear Strength and Plasticity Index Was Described by the Second-Moment Statistics (Mean and Variance). Meanwhile, the Correlation between the Undrained Shear Strength and Plasticity Index Was Established and Compared with Other Published Empirical Equations. the Results from the Soil Variability Analysis Provide a Framework to the Reliability-Based Design. © 2011 ASCE.
