摘　　要：长江下游流域的堤防因受梅雨汛期的影响,需在汛期后及时对其进行形变分析,掌握堤防的安全状况,传统方式主要依靠人工巡视,难以发现细微的形变,从而影响对其安全状况的判断。因此,提出一种基于静态GPS测量技术的堤防微观监测方法,并且在张家港市境内42.33 km的长江堤防上进行应用。应用结果表明,该方法能够准确测量固定堤防断面点的高精度、实时性的平面坐标,进而经过对比、分析后发现细微的形变,与实地核查一致,可为堤防的管理与决策提供参考,保障安全运营。Due to the influence of Meiyu flood season,the embankment in the lower reaches of the Yangtze River needed to be analyzed in time after the flood season to grasp the safety status of the embankment.The traditional way mainly relied on manual inspection,which was difficult to find subtle deformation,thus affecting the judgment of its safety status.Therefore,a micro monitoring method based on GPS measurement method was proposed,which applied in the 42.33km Yangtze River Dyke in Zhangjiagang City.The application results showed that this method could accurately measure the high-precision and real-time plane coordinates of the fixed embankment section points.After comparison and analysis,it's found that the slight deformation was consistent with the field verification,which could provide reference for the management and decision-making of the embankment and ensure the safe operation.
