摘　　要：为解决复杂观测条件下长距离混凝土坝视准线观测精度不满足规范要求的问题,提出基于高精度测量机器人和正倒垂监测数据的“分段对向小角度法”。通过试运行观测数据分析,各测点位移变幅符合大坝变形规律,且位移量与气温、水位的相关性强弱与监测点位置有关。观测精度分析表明:该方法能满足1mm的观测精度要求,故“全自动分段对向小角度法”为提高长距离混凝土坝视准线观测精度提供了有效途径。In order to solve the problem that the sight line observation accuracy of long-distance concrete dam under complex observation conditions does not meet the requirements of the specification,a“segmented opposite small angle method”based on high-precision measurement robots and positive and negative monitoring data is proposed.Through the analysis of trial operation observation data,the displacement amplitude of each measuring point conforms to the deformation law of the dam,and the correlation between the displacement and the air temperature and water level is related to the location of the monitoring point.The observation accuracy analysis shows that this method can meet the observation accuracy requirement of 1mm,so the“fully automatic segmented opposite small angle method”provides an effective way to improve the sight line observation accuracy of long-distance concrete dams.
