通过实地考察、现场测试、技术改进及各个环节的优化措施,降低了GNSS自动化监测系统在小湾拱坝安全监测中的一系列误差,提高了测量精度。结合小湾工程实际,总结了建立完善的GNSS监测系统在施工、安装、调试中的一些经验,充分发挥了GNSS监测系统自身优点。通过与全站仪、正倒垂线测量数据对比,较好地印证了GNSS监测系统在小湾拱坝中的成功应用,对实时准确监测小湾大坝变形状态、保障流域安全具有特别重大的意义。
Through field investigation, field testing, technical improvement and optimization measures in all aspects, a series of errors of GNSS automatic monitoring system in the safety monitoring of Xiaowan Arch Dam are reduced and the measurement accuracy is improved. According to the actual situation of Xiaowan project, some experiences in construction, installation and commissioning of the established GNSS monitoring system are summarized, and the advantages of GNSS monitoring system are given full play. Through the comparison with total station and inverted vertical measurement data, the successful application of GNSS monitoring system in Xiaowan arch dam is confirmed. It is particularly important for monitoring the deformation status of Xiaowan dam in real time and ensuring the safety of the basin significance.
