【摘要】 在Mononobe-Okabe理论的基础上,采用拟静力分析法和水平层分析法,推出地震条件下黏性均质填土挡土墙的被动土压力强度分布函数计算式、土压力合力作用点位置高度计算式和墙后土体破裂角计算式。通过与朗肯和库伦土压力理论算例的计算结果进行比较,验证了所推出的计算式的合理性和正确性。因公式推求的条件更为一般化,限制性较小,适用性较强。更多还原

【Abstract】 Based on Mononobe-Okabe Theory, this paper derived the formula calculating the strength distribution function of passive earth pressure of homogeneous clay soil filled retaining wall in seismic condition,the height of point,at which the resultant earth pressure is applied,and the rupture angle of soil mass behind the wall. Through the comparison with the calculation results of examples depending on Rankine and Coulomb’s earth pressure theory,the reasonableness and correctness of these formulas were verified. As the result of the more general conditions and less restrictions for derivation of the formula,they have more extensive applicability.更多还原
