以Mononobe-Okabe假定为前提,利用水平层分析法,建立了地震荷载作用下刚性挡土墙平移模式下的主动土压力强度的一阶微分方程,并求得非线性分布解.所得合力公式与Mononobe-Okabe公式完全相同.分析结果表明,地震系数对土压力强度分布有很大影响.另外,通过探讨填土的内摩擦角、墙背的摩擦角以及地震系数对主动土压力合力作用点高度的影响,认为Mononobe-Okabe理论对于平移模式下刚性挡土墙的抗倾覆稳定性是偏于危险的.

Based on the Mononobe-Okabe hypothesis, the horizontal layer analysis method is used to establish the first-order differential equation of the active earth pressure intensity under the translational mode of the rigid retaining wall under seismic loading, and the nonlinear distribution solution is obtained. The resulting resultant force formula is exactly the same as the Mononobe-Okabe formula. The analysis results show that the seismic coefficient has a great influence on the distribution of earth pressure intensity. In addition, by discussing the influence of the internal friction angle of the fill, the friction angle of the wall back and the seismic coefficient on the height of the active earth pressure resultant action point, it is considered that the Mononobe-Okabe theory is dangerous for the overturning stability of rigid retaining walls in translation mode.
