摘　　要：本文主要介绍了长江新生洲洲头坝体利用全球导航卫星系统(GNSS)变形监测方法。通过对坝体的变形观测网多次资料的平差计算,对坝体的稳定性进行稳定性分析。监测测量结果分析说明:坝体在水平方向位移相对稳定,垂直位移是因现场施工造成沉降引起的。提出了新生洲洲头坝体安全运营建议。This paper mainly introduced the deformation monitoring method of the dam body at the head of Xinshengzhou of the Yangtze River by using the global navigation satellite system(GNSS).The stability of the dam body was analyzed by the adjustment calculation of the multiple data of the deformation observation network.The analysis of monitoring and measurement results showed that the displacement of the dam body was relatively stable in the horizontal direction,and the vertical displacement was caused by the settlement caused by the on-site construction.The suggestions for the safe operation of the dam body in Xinshengzhou were put forward.
