And it can be applied to the urban earthquake prevention and disaster mitigation. Firstly, the empirical equation of cyclic resistance ratio CRR of saturated sands with different probability levels is utilized to evaluate the earthquake-induced site liquefaction potential. Secondly, a “block” data structure is adopted to describe the 3D liquefaction potential entity. Thirdly, visual 3D visualization modeling for the earthquake-induced site liquefaction potential can be realized based on the Kriging interpolation method and volume rendering technique. The research described in this paper shows that: (1) When 3D liquefaction potential entity is partitioned by the “block” data model, the Kriging method can be adopted to realize 3D interpolation. Therefore, the latent distribution of the site liquefaction potential beyond the observation boreholes can be evaluated. (2) Based on the probability evaluation results and volume rendering technique, the Kriging interpolation results are displayed in different color marks to indicate the risk extent of the site liquefaction potential. Thereby, the spatial distributing characteristics and variety trend of the site liquefaction potential can be displayed in the 3D graphic form. And also, the 2D profile cutting and 3D body incision can be generated automatically.
