摘要
根据刚性挡土墙模型试验中主动土压力的分布规律和主动土压力产生的机理 ,利用弹塑性理论 ,引入接触面单元和弹簧边界条件 ,建立了刚性挡土墙主动土压力的计算模式。理论计算与模型试验结果能很好地吻合。
An elasto plastic numberical calculation model for earth prssure acting on retaining wall has been established according to the results of model tests and the mechanism of active earth prssure. The boundaries between soil and retaining wall, soil and floor are simulated by interface elements and springs. Numberical results are agree with experiments. Calculation shows the influence of friction between soil and floor can cause the pressure decreasing but only occurs near the bottom area in engineering.
