Abstract | This paper presents a liquefaction risk analysis in terms of the percent defective in ground improvement. In this paper, the liquefaction potential of artificially solidified ground is analyzed statis...tically 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 random field numerical limit analysis. The annual liquefaction risk is calculated by multiplying the liquefaction potential with the damage costs caused by a partial liquefaction. Effects of percent defective in ground improvement on the liquefaction risk of anti-liquefaction ground investigated using the hazard curve, fragility curve induced by liquefaction, and liquefaction risk curve. Moreover, the percent defective in ground improvement was discussed from the viewpoint of the quality verification for the construction of anti-liquefaction ground. Finally, Finally, ideal strength of ground improvement was decided based on minimization of expected total cost.show more |
