Shaking Table Tests on a Deformation Mitigation Method for Road Embankment during Liquefaction by Using Gravel and Geosynthetics
Small scale shaking table tests in a 1-g gravity field were carried out to evaluate the effectiveness of deformation mitigation method for road embankment during liquefaction by using gyosynthetics sandwiched between gravel. The gravel layer could dissipate the excess pore water pressure during liquefaction immediately, and restrained the shear deformation under the embankment because of its high permeability. Furthermore, the composite layer which consisted of the gravel with geosynthetics could perform as a rigid plate with high permeability. As a result, the improved layer could restrain the deformation of embankment, and this effect could keep shape of embankment.
