本文介绍了在动载作用下砂土中水平应力变化的实验研究成果。在一个垂直振动的振动台上对３号渥太华砂样进行振动，用一个改装的固结仪环测试静止水平应力。实验结果表明：对正常固结砂，水平应力随振动时间增加而增加，增加的数值与砂的密实度和振动强度有关。对于静止土压力系数高的超固结砂，水平应力随振动时间增加而降低。论文中还给出了试验样品的应力路径
In this paper, the experimental results of horizontal stress change in sandy soil under dynamic loading are introduced. The No. 3 Ottawa sand sample was vibrated on a vertically vibrating table and tested for static horizontal stress using a modified consolidator ring. The experimental results show that for normal consolidated sand, the horizontal stress increases with the increase of vibration time, and the increasing value is related to the compactness and vibration intensity of sand. For over-consolidated sand with high static earth pressure coefficient, the horizontal stress decreases with the increase of vibration time. The paper also gives the stress path of the test sample
