2014年底,南水北调中线干线工程全线正式通水,冬季冰期输水面临渠道结冰问题。为研究中线干线冬季冰期安全输水问题,于2014~2015年度冬季开展了冰情原型观测,获得了冬季冰期输水的水力参数、气象参数和冰情特征等第一手现场数据,掌握了暖冬气候条件、小流量输水工况下中线干线结冰、封冻和开河过程的基本规律。为中线工程冬季安全输水运行积累了经验,可为制定冰期调度方案和编制防凌减灾措施提供依据。
2014年底,南水北調中線榦線工程全線正式通水,鼕季冰期輸水麵臨渠道結冰問題。為研究中線榦線鼕季冰期安全輸水問題,于2014~2015年度鼕季開展瞭冰情原型觀測,穫得瞭鼕季冰期輸水的水力參數、氣象參數和冰情特徵等第一手現場數據,掌握瞭暖鼕氣候條件、小流量輸水工況下中線榦線結冰、封凍和開河過程的基本規律。為中線工程鼕季安全輸水運行積纍瞭經驗,可為製定冰期調度方案和編製防凌減災措施提供依據。

The Middle Route Project of South-to-North Water Diversion began to deliver water from Danjiangkou Reservoir to northern China since the end of 2014. The freezing ice is a key problem for the water division in winter, so the ice prototype monitoring was carried out in the winter of 2014 to 2015. Through the monitoring, we collected the hydraulic parameters, meteor-ological data and ice data. Based on the analysis of the monitoring data, the basic discipline of ice formation, freeze-up and break-up of the channel under small flow in warm winter was mastered. The results could provide reference for drafting operation scheme and disaster mitigation plan of the main channel in icing period, and accumulate experiences for safe water diversion in winter of the main channel.
