A Validation Exercise for a Footing Supported by Leyden Clay Fill: A Comparison of Large-Scale Testing and the Finite Element Method
Publication: Rocky Mountain Geo-Conference 2022
ABSTRACT
Validation exercises for computational analyses in geotechnical engineering are essential. Complex computational analysis methods are increasingly implemented in engineering practice with too little validation data. Since about 2012, the Center for Geotechnical Engineering Science (CGES) at the University of Colorado Denver (UCD) has attacked the validation problem by developing large-scale testing systems for soil-structure interaction problems in concert with finite element analyses. This paper presents a validation exercise for an isolated footing, under vertical loading, on Leyden Clay fill, behind an at-rest retaining wall. The validation experiment was performed in a large-scale, soil-structure interaction, testing system known as the “Tiger Cage”. This paper presents and compares the execution of the validation experiment and the laboratory testing for the Leyden Clay fill with three-dimensional finite element analysis, using the TrueGrid and LS-DYNA software programs.
