This paper describes the numerical procedure of solving liquefiable ground problems involving RC structures for unsaturated to saturated porous media and its verification and application based on a three-dimensional effective stress analysis method. The following conclusions are obtained from this study: (1) The developed procedure accurately reproduced the unsaturated seepage flow behavior, based on comparing laboratory test results with seepage flow analytical results; (2) The applicability of the procedure considering the material nonlinearity of both the soil and RC structure is verified, and an underground RC structure surrounded by unsaturated and saturated liquefiable ground is simulated. Moreover, the rational and acceptable seismic behavior of an underground RC structure is reproduced under a large-scale earthquake.
