A Database for the Experimental Study of Earthquake-Induced Liquefaction and Lateral Spreading in Sands

摘要

Centrifuge and large-scale testing in geotechnical engineering are very useful tools for modeling soil behavior under different loading conditions, particularly under earthquake loading. The paper presents an extensive database of nine centrifuge and large-scale liquefaction experiments performed both at the geotechnical centrifuge testing facility at Rensselaer Polytechnic Institute (RPI) and the large-scale testing facility at the University at Buffalo (UB). The database described herein was generated using the NEEShub online DataStore tool under the name "CENSEIS: Centrifuge and Large (Full)-Scale Modeling of Seismic Pore Pressures in Sands" (DOI: http://dx.doi.org/10.4231/D3GF0MX4F). The paper discusses the tools and materials used in the experiments along with an explanation of each item in the database. Sample analyses are also presented in the paper to give an insight on the capabilities of the database for numerical and analytical applications. The paper is concluded with some possible applications along with tips and limitations of the database.
