- 对海底饱和砂土发生液化时，埋于其中的管道运动规律进行了探讨，利用振动台上进行了模型试验。根据试验结果和建立的运动方程，获得阻力系数与圆管形状的关系，并计算了圆管所受到的拖曳力。
The movement manner of pipeline buried under saturated sandy soil is studied,when soil is liquefied,by making model test using vibration bench.Based on the test results and movement equation established,the relationship between drag coefficient and tubular shape is obtained and the drag force imposed on pipe is calculated.2000,1(1): 11-14 收稿日期：1999-5-18分类号：TE973.92参考文献：
