摘　　要：主要研究挡土墙位移对土压力的影响,通过室内模型试验,实测了挡墙不同位移模式下土压力的相关数据,绘制出土压力沿墙高的分布曲线,并在极限状态下与古典朗肯土压力理论结果进行了对比分析。研究结果表明:在不同位移模式下,主动和被动土压力都不是理论上的线性分布,而各有特点。This paper mainly studies effect of retaining wall displacement on soil pressure. Through indoor model tests, the data in respect of soil pressure under different displacement modes of retaining wall is measured and the distribution curve of the pressure along the wall height is drawn; then comparing to the result derived from Rankine＇s earth pressure theory, the analysis at ultimate state is conducted. The result shows that under different displacement modes, the active and passive soil pressures do not present theoretical linear distribution, but have respective characteristics.

关 键 词：主动土压力 被动土压力 静止土压力 极限平衡状态 应力应变
