This paper presents a risk-based procedure for the liquefaction assessment of artificially solidified ground. In this paper, the liquefaction potential of artificially solidified ground is analyzed statistically using Monte Carlo Simulation of the nonlinear earthquake response analysis considering the spatial variability of soil properties. Damage cost induced by a partial liquefaction in the solidified ground is estimated based on the reduction of the seismic bearing capacity obtained by the random field numerical limit analyses. Finally, liquefaction risk curve is calculated by multiplying the liquefaction potential with the damage cost and the probability of earthquake. The main conclusions are as follows: 1) The spatial variability of soil properties in artificially solidified ground affects greatly the liquefaction fragility curve and liquefaction risk curve respectively. 2) Annual liquefaction risk increases with increasing the spatial variability of shear strength and also depends on the characteristic of earthquake hazard curve.
