初始冰塞厚度与水流条件及冰流量关系的试验研究

初始冰塞厚度是冰塞研究的基础，对冰塞的后期增厚及平衡冰塞的形成与发展均有重要的影响。本文通过水槽试验，对初始冰塞厚度的形成及变化机理进行了试验研究，揭示了初始冰塞厚度与水流条件和冰流量等因素间的相互关系。试验表明:在室内水槽中定性研究冰塞的形成与发展机理等变化规律时，使用石蜡模型冰材料是可行的

A study on the relationship about initial ice jam thick ness with its stream conditions and ice discharge

The initial ice jam thickness is a basic parameter in research of ice jam character and has important influences on its thickening, developing or in equilibrium later on. In this paper, flume experiments on the formation of initial ice jam thickness and its varying mechanism were carried out, brought to light the relations between factors of initial ice jam thickness, flow condition and ice discharge etc.. Experimental results revealed that it is feasible to use paraffin instead of ice in flume experiments to conduct qualitative researches on the formation and developing mechanism of ice jams.
