摘要
对黄金峡水利枢纽坝肩边坡GNSS自动化变形监测系统的设备选型、参考站选址、通信方式等进行了分析总结。在吸收借鉴国内同类工程运用GNSS系统的经验和相关研究成果的基础上,该系统采用GPS/BDS/Glonass多星数据混合解算、双基线平差等方法,使边坡监测站在观星截止高度角较大的情况下观测精度满足规范对一级边坡变形监测的精度要求。通过实施GNSS自动化变形监测系统,可以及时掌握边坡的变形规律,预测边坡及滑坡可能变化的范围及变化趋势,并能够及时采取相应的处理措施,为黄金峡水利枢纽施工期安全生产提供技术保障和依据。
This paper analyzed and summarized the equipment selection,reference station location and communication scheme of GNSS de⁃formation monitoring automation system of Huangjinxia Hydro Junction project.It pointed out that on the basis of absorbing the experience and relevant research of GNSS system of similar projects in China,the system adopted GPS/BDS/GLONASS multi satellite data hybrid solution and double baseline adjustment to make the slope monitoring station watch the stars when the cut-off angle is large,the observation accuracy can meet the accuracy requirements of the specification for the first grade slope.Through the implementation of GNSS deformation monitoring automation system,we can timely grasp the deformation law of slope,predict the possible change range and trend of slope and landslide and take corresponding treatment measures in time,so as to provide technical guarantee and basis for the safety production of Huangjinxia Hydro Junction Project during the construction period.
