Abstract
In this study, to solve a problem that cannot consider the contribution effect of each layers when the apparent earth pressure in homogeneous ground is applied to multi-layered ground, the measured earth pressures at World were investigated and analyzed. It has been confirmed that the apparent earth pressure in mulit-layered ground is different from single ground and that the extra layer's contribution to the earth pressure cannot be considered. The conventional method of calculating the apparent earth pressure for single ground was extended to mulit-layered ground, and proposed and verified the applicable method for both single and mulit-layered ground. The proposed methods predicted the earth pressure closer to the measurements at the excavation depth of 0.1Z/H or below, and the prediction reliability was evaluated to be better than the conventional method. Among the proposed methods, the method of considering the area ratio of the active failure has a geotechnical validity and predicts the most similar results to the actual earth pressure. To confirm the applicability of the proposed methods, it was presented by comparing and analyzing the results of the proposed methods with the conventional method for the actual case.
