摘　　要：预应力技术在桥梁工程中应用极为普遍,其施工质量直接影响到桥梁的安全性、可靠性和长期使用寿命。桥梁预应力检测及控制技术研究是目前工程研究的热点方向,全国众多学者结合现代控制技术开展了预应力工程质量的研究工作,工程应用上取得了满意的成果。广东省珠三角地区某高速公路开展桥梁锚下预应力检测与控制技术研究专题,拟通过真实准确数据发现并即时解决现场技术问题,强化施工工艺,消除工程隐患,使整束有效预应力和同束不均匀、同断面不均匀度都得到全面控制。Prestress technology is widely applied in bridge engineering,the construction quality of which directly affects the safety of the bridge,reliability and long service life.As prestress detection and control technology is the focus of engineering study trend,many scholars nationwide has conduct studies on prestressed engineering quality and achieved satisfactory results.This paper introduces a specific study on detection and control technology of highway bridge anchorage prestress in Guangdong Pearl River Delta region,aiming at finding out and solving the technical problems,strengthening the construction process and eliminating project risks to control the overall factors,including the effective prestress with the whole bundle of beam and the unevenness of the different beams and the same section.

关 键 词：预应力检测 有效预应力控制 不均匀度
