摘　　要：崖门大桥已通车15年,目前处于良好的工作状态。特别是定期和日常养护检查发现的斜拉索质量病害能及时维护,锚具除锈更换专用油脂,PE护套表面刮损修复;斜拉索钢套筒上移,增设了螺旋线抑制风雨振;在防雨罩上方增设气囊压力式密封,效果较好,可提高结构耐久性,延长桥梁使用寿命。Yamen Bridge has been open to traffic for 15 years and is currently in good service condition. In particular,as soon as diseases of the cables are found by the regular and daily maintenance check,timely maintenance has been carried out,the rust of anchors is removed and replaced with special grease,the scratched surface of PE sheath is repaired. The steel sleeve of the cable-stayed cable is moved upward and the spiral line controlling rain wind induced vibration is added. The airbag pressure seal is added on the upward side of the rainproof cover,with good effect which can improve the durability of the structure and extend the service life of the bridge.
