Analysis for the Deformation of the Damaged Embankments during the 2004 Niigataken-Chuetsu Earthquake by Using Stress-Strain Curves of Liquefied Sands or Softened Clays
Abstract Stress-strain curves of liquefied sands and softened clays were obtained by cyclic torsional shear tests. In the tests, 20 cycles of loadings were applied at first then a monotonic loading was applied. Shear modulus of the liquefied sands or softened clays, G1, was evaluated based on the stress-strain curves during the monotonic loading. Then, a relationship among cyclic stress ratio to cause 7.5 % of double amplitude of shear strain, RL(γDA=7.5 %, NL=20), severity of liquefaction, FL and G1/σc’ were derived. Based on the relationship, analysis for the deformation of damaged road embankment during the 2004 Niigataken-chuetsu earthquake, was conducted. Analyzed deformation was fairly coincided with the measured deformation.
