1959年12月26日,丹江口水利枢纽截流工程胜利合龙。为施工与科研服务的水文测验工作,同样也获得了辉煌的胜利。自11月1日截流工程开始至12月26日合龙止,一个多月的时间内,仅水道地形就测了45次。截流紧张时,每5～15分钟测流速一次。壩区附近的19组水尺,每15～30分钟就观测一次水位。其余截流时的水文资料,如龙口水面曲线。河段流向、最大流速与前沿流速的变化过程,出现的时间和平面位置,戗堤进钻中的水道地形,戗堤的渗透流量等,均已全面测到,对施工进度安排起了重大的参谋作用。这些资料不仅直接指导了
December 26, 1959, Danjiangkou Water Control Project closure project won the victory. For the construction and scientific research hydrological test work, also won a brilliant victory. Since November 1, the closure project started until December 26, only more than a month’s time, the watercourse topography measured 45 times. Closure of tension, every 5 to 15 minutes measured flow rate once. 19 groups near the dam, every 15 to 30 minutes to observe a water level. The rest of the hydrological data, such as Longkou water surface curve. River flow direction, the maximum flow velocity and the front flow rate of change process, the emergence of the time and plane position, embankment into the drilling of the waterway topography, dike infiltration flow, etc., have been fully measured, the construction schedule has played a significant Staff role. These materials not only direct guidance
