平衡冰塞输冰的试验研究

A Study on Ice Jam in Balance Transporting Discharge

冰塞的出现 ,改变了河流的水力条件、热力条件及边界条件 ,常产生凌洪灾害 ,影响发电、航运及河床演变。平衡冰塞是冰塞发展与演变过程中的一个阶段 ,通常对开河冰塞有重要的影响 ,根据水槽试验和理论分析 ,对从初始冰塞演变到平衡冰塞的过程和影响因子进行了试验研究 ,揭示了平衡冰塞厚度及平衡时间与水流条件和冰流量等因素的相互关系 ,从理论上分析了计算输冰量的定性形式。研究成果对于工程实际有一定的参考意义。

Balance ice jam is a phase during ice jam evolution. It has important effect on opening ice jam, based on flume experiments and analysis, the factor and course from initial ice jam to balance ice jam were studied, correlation about balance thickness of ice jam with balance time and flow condition and ice flow were unveil the right format of calculating ice discharge is published. Research fruit has action on fact.
