摘要
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 the field investigation,field test,technical improvement and each link of the measures,reduced a series of error about the GNSS automatic monitoring system in xiaowan arch dam safety monitoring,improved the measuring accuracy.Combined with the engineering practice of xiaowan,summarized experiences about construction,installation and debugging in establishing perfect GNSS monitoring system,gived full play to the advantages of GNSS monitoring system itself.Contrastd the measurement data with Electronic Total Station and vertical line,good proved the successful application about GNSS monitoring system in xiaowan,which has special significance to monitor deformation condition of xiaowan dam accurately,also important to ensure the safety of the river basin.
