SEISMIC SETTLEMENT ESTIMATION ON PARTIALLY IMPROVED GROUND USING SHAKING TABLE
The anti-liquefaction ground improved by cement-mixing and permeable-grouting shows the spatial variability of liquefaction strength resulting from the spatial variability of original soil profile before treatment, the non-uniformity of mixing and grouting, etc. The seismic behavior of improved ground with the spatial variability of liquefaction strength,however, has not been fully clarified. In this paper, in order to evaluate effects of spatial variability of liquefaction strength on the seismic behavior of improved ground, a series of model experiments has been carried out through investigating the seismic behavior of partially improved ground using shaking table test. Moreover, the estimation of seismic settlement considering the depth distribution of vertical strain in terms of 1 dimensional (1D) and 2 dimensional (2D) improvement patterns has been proposed. It can be seen that estimated seismic settlement from 2D improvement pattern shows better agreement with observed settlement than 1D estimation.
