Study on liquefaction of saturated loess by in-situ explosion test

Liquefaction testing at a saturated loess site was performed under the simulated earthquake ground motioninduced by artificial explosions with micro-time intervals. The time histories of ground acceleration, pore water pressure and theultimate value of residual strain were recorded and measured. The...

Description
Summary:Liquefaction testing at a saturated loess site was performed under the simulated earthquake ground motioninduced by artificial explosions with micro-time intervals. The time histories of ground acceleration, pore water pressure and theultimate value of residual strain were recorded and measured. The modified FEQdrain computation software was used toanalyze the liquefaction. Both the test and the analysis confum the objective occurrence of loess liquefaction. Furthermore, thereliability of the method of the loess liquefaction analysis based on FEQdrain and the model of pore water pressure developmentof saturated loess are examined.
