摘要
巴彦高勒河段位于黄河内蒙古河段上段 ,封河时容易形成冰塞 ,特别是自 1986年以来 ,巴彦高勒河段几乎连年冬季形成严重冰塞 ,灾害损失惨重 .本文详细分析了 1986年前后巴彦高勒河段水力条件、热力条件和河道边界条件三方面的变化 ,从而研究冰塞的形成原因及条件 。
Bayangaole section is located at the upper reach of Yellow River. Ice jam always happened in winter at this section since 1986 and formed serious disasters. In this paper, the variations of hydraulic factors,thermal factors as well as the boundary conditions of channel are analyzed in detail and the causes and conditions of ice jam formation are studied.
