本文阐述了汾河干流头马营至河岔河段1996~1997年冰期沿程冰情、水温、流量变化。分析了静乐、河岔水文站在冰期受气温日变化影响的流量日变化规律。分析了1996~1997年冰情的代表性以及引黄后发生冰塞、冰坝的可能性。用历年汾河上游冰期水文资料,对历年冰期河槽储冰量进行了分析计算,探讨了河槽结冰对流量的影响,最后提出了冰期输水措施和建议。
This article elaborates the changes of ice conditions, water temperature and flow along the period from 1996 to 1997 during the period from Tamama camp to the river Chahe section of Fenhe River. The daily variation of the flow rate influenced by the air temperature in Jingle and Hacha hydrological stations during glacial period was analyzed. This paper analyzes the representativeness of ice conditions from 1996 to 1997 and the possibility of slugging and ice dams after the Yellow River Diversion. Based on the glacial hydrological data of the upper Fenhe River in the past years, the ice storage in the ice sheets in the past glacial period was analyzed and calculated, and the influence of the river channel icing on the flow rate was discussed. Finally, the measures and suggestions for water conveyance in the ice age were proposed.
