摘　　要：水电站混凝土闸墩预应力锚索空间结构复杂,影响施工质量因素较多。根据小峡电站的设计特点,从施工的角度阐明了如何从控制埋管、材质及张拉设备检验标定、钢绞线理论伸长值计算、灌浆回填等方面来确保设计意图的有效贯彻,对施工效率和工程质量的提高积累了一定的经验。Hydropower station's concrete pier tendon has sophisticated spatial structure and the factors affecting construction quality are numerous. On the basis of design features of Xiaoxia hydropower station and from the view point of construction the article throws light on how to ensure effective execution of design intentions by controlling embedded pipes and material quality and in respects of calibration of stretching apparatus, calculation of strand theoretic elongation value and grouting backfill. Certain experience is obtained on enhancing construction efficiency and quality.
