| 摘 要： | 针对平动位移模式下的刚性挡土墙墙后填土为黏性土的情况,研究了考虑平动位移效应的非极限状态土压力计算.对平动模式下未达到极限位移的挡土墙,结合前人提出的考虑位移效应时,墙后填土内摩擦角及墙土接触面上外摩擦角之间的关系,用水平层法分析了墙后土楔的受力情况,得到了考虑位移效应的非极限状态的黏性土主(被)动土压力计算公式,通过比较发现,理论公式与实验结果较吻合. |
| 关 键 词： | 刚性挡土墙 平动模式 黏性填土 土压力 非极限状态 |

| Abstract: | Focusing on cohesive backfill on rigid retaining wall under translation movement mode,the earth pressure under non-limit state considering translational movement effect is studied.To retaining wall which doesn't get the limit movement under translational mode,based on the relationship between inner friction angle of backfill and outer friction angle on interface between wall and backfill,the mechanical analysis of soil wedge is given by using slice element method,and the formulation for calculating active and passive earth pressure of cohesive backfill soils on non-limit state is established.Comparison of the calculated results with the measured results from model experiment shows that the calculated result has a good agreement with the measured results from model experiment. |
| Keywords: | rigid retaining wall translational mode cohesive backfill soils earth pressure non-limit state |
