摘要
Abstract
Based on Mononobe-Okabe's postulation, the first-order differential equation for passive earth pressure on the retaining wall was set up for the translation(T)mode, movement modes of rotation around base(RB)and rotation around top (RT) by analyzing slice elements extracted from sliding soil wedge; and the formulas for calculating of the unit earth pressure, the resultant earth pressure and the action point of resultant pressure were given. The comparison between calculated results by the present formulas and Coulomb's theory shows that the unit earth pressure is nonlinearly distributed; and that the distance from the action point of resultant pressure to the base of wall increases with the order of (RB)mode, (T)mode, and (RT) mode.关键词
