摘　　要：河南省某水库溢洪道工程闸墩混凝土采用预应力锚束施工,从施工工艺控制和张拉过程观测数值的理论分析两个方面论述了预应力锚束的施工流程和质量控制方法,为预应力锚束的现场施工提供了有价值的参考方案。The prestressed anchor cable scheme was used in the pier concrete of reservoir spillway engineering. From the con- struction technology control and numerical theory analysis of tension process monitoring data, the construction process and quality control was discussed, which was valuable for the in situ construction of prestressed anchor cable.
