    流土的模拟试验

    THE SIMULATION TESTING ON FLOWING SAND

    • 摘要: 介绍了砂槽模型比例的确定.通过砂槽模型一、二的原型试验,详细介绍了试验现象,分析了产生这些现象的原因.从试验总结出流土通道上下游两端的水头值和渗流坡降的分布特点,从对比试验得出三个试验参数:砂的密实度、上夜盖层的重量和渗流水头上升的速度对流土破坏的影响.

       

      Abstract: This thesis introduces a way to decide the scale of the sand model. The experiments phenomena of two modelsis preseated and explained. The experiments data show the distribution of the water head and the seepage gradient near the flowing sand channel. Additionally, the effects,by the sand porosity, the weight of the overlaid soil and the ascending speed of the seepage Bead produce on flowing sand, are reoorgnized by contrasting experiments.
