Typical soil-water coupled analyses of saturated soils are mostly based on u-p formulation, which neglects inertial effect of pore water. Instead, we have developed “u-w-p formulation”-based analysis for obtaining exact solutions. We’ve included the damped-vibrational solution of an immediate settlement in case of high-permeable soils with confirmations of the efficacy of our formulations. Here we indicate that the u-w-p formulation gives specific variation of pore water pressure at the initial of the settlement analysis and propose a one-dimensional model for understanding the phenomenon.
