摘　　要：丹江口大坝加高工程施工过程中,混凝土坝右联转弯坝段高程143m处理采取了锯缝方案。锯缝方案实施后,选择在右联1号、右1号和右2号坝段143m高程水平裂缝布设了监测设施,以进一步的观测锯缝方案的实施效果。本文介绍了监测设施的布置,并通过在大坝加高施工期的观测成果分析,对丹江口大坝右联转弯坝段143m高程水平裂缝处理效果作了监测评价。Abstract： Keff program was adopted in processing concrete dam right-connection turning-dam section elevation 143m in the construction process of Danjiangkou Dam Heightening Project. After the kerf program was implemented, monitoring facilities are distributed in horizontal cracks of 143m elevation in right-connection No. 1, right No. 1 and right No. 2 dam sections, thereby further observing the implementation effect of the kerf program. The layout of the monitoring facilities is introduced in the paper. The observation results in the dam heightening construction period are analyzed for monitoring analysis on treatment effect of Danjiangkou Dam Right-connection Turning-dam Section 143m Elevation Horizontal Crack.
