边坡锚索自动化张拉施工工艺优化与工程应用

Optimization and Engineering Application of Automation Tensioning Construction Technology for Slope Anchorage Cable

摘要

边坡预应力锚索是水利水电工程高陡边坡稳定的常用支护措施，但人工控压张拉易受操作波动与读数误差影响，常出现分级加载不匀、锁定力离散与复核记录缺失。自动化张拉以成套千斤顶和泵站为核心，把分级加压、持荷、伸长量量测与锁定组织为统一节拍，使张拉力控制与伸长值校核能够稳定执行。本文结合中国水电站坝肩与厂房边坡施工实践，围绕设备匹配、分级张拉和锁定损失补偿提出可实施的工艺优化要点，并给出工程应用的组织与验收策略。

Abstract

Prestressed anchor cables are commonly used support measures for the stability of high and steep slopes in hydraulic and hydroelectric engineering. However, manual pressure control and tensioning are prone to operational fluctuations and reading errors, often resulting in uneven graded loading, discrete locking forces, and missing verification records. Automated tensioning, centered on a complete set of jacks and pump stations, integrates graded pressure application, load holding, elongation measurement, and locking into a unified rhythm, enabling stable execution of tension control and elongation verification. This paper combines the construction practices of China’s hydropower station shoulder and powerhouse slopes, proposing implementable process optimization points focusing on equipment matching, graded tensioning, and compensation for locking losses, and provides organizational and acceptance strategies for engineering applications.
