Numerical Simulations of Geotechnical Centrifuge Modeling of Seismic Earth Pressures on an Underground Restrained Structure
Centrifuge model tests on rectangular structures buried in unsaturated soils are being conducted to simulate an underground restrained wall subject to earthquake shaking. In order to compare the centrifuge testing results with soil-structure-interaction (SSI) results from a numerical modeling approach that is becoming increasingly common for practical design, a pre-centrifuge testing Class A prediction has been performed. This prediction will enable: (1) comparison of the "blind" numerical modeling with the centrifuge testing results; (2) engineers to identify any potential analysis issues with emerging numerical modeling approaches; and (3) developing design improvements for underground restrained walls. Class A prediction results are presented for a buried rectangular structure with zero and 5 feet of soil above the roof, respectively. The centrifuge results, additional analytical studies, and recommendations for seismic analysis and design improvements will be published elsewhere after completion of the centrifuge testing program.
