The model stratums mainly included miscellaneous filling soil surface, interaction stratum of silty clay, silt and fine sand and pebble round gravel at the bottom of station tunnel.
模型介质材料分别模拟地表杂填土层，粉质黏土、粉土、粉细砂互层和车站隧道底部的卵石圆砾层；

The numerical model successfully predicts the change turning point of clouds area and diffuse width before the clouds touch the bottom, which is specially important to the design of silt-fence.
计算模型成功地预测了云团触底前面积和扩散宽度变化转折点，对拦泥帷幕的设计将有重要意义。

Apart from this, it discusses the starting current velocity of bottom sediment affected with vertical waves as well as the settling velocity of silt particles.
