The graphs of earth-pressure-distribution obtained by seismic observations in recent years are different from the one of the theoretical solution proposed by Mononobe and Okabe. This paper examines the results obtained from the analytical solution that the authors have formulated with compering to experiments performed by Kazama The increment of dynamic-earth-pressure subject to harmonic excitation generally shows the maximum value at the surface of the ground, then decreases with lager distance from the surface and changes its signs below some depth. Therefore the curves for absolute values of pressure-increments show zero or small value around that depth. The graphs of those calculated for the case of rotational excitation of underground walls qualitatively correspond to the experimental results during sinusoidal excitation.
