摘要
本文根据黄河河曲段六年的冰情资料，分析研究了该河段冰塞演变及冰期水位变化的规律，建立了冰塞运动有关参数的关系式．在此基础上，对实验室模拟冰塞的运动进行了分析研究．研究表明：实验室模拟冰塞的演变规律与天然冰塞的演变规律相似．
Based on the data observed for six years in Hequ section on the Yellow River, the laws of evolution of ice jam and variation of water level are investigated. A formula to calculate the parameters related to ice jam movement is established. The ice jam movement is also simulated in laboratory. Comparison between data and laboratory testing results reveals that the similarity of the evolution laws of the ice jam in laboratory is good.
