摘要
针对苗家坝水电站实际情况,采用以测量机器人为主、GNSS为辅的方案取代人工测量,配套研发了大坝变形监测智能采集分析系统,从观测方法、测量结果修正、仪器保护等方面开展探索实践,形成具有观测时段自寻优、精密仪器自防护等典型特点的三维形变智能监测系统,具备全天候、全时段自动监测能力,实现了外部变形智能监测和数据实时处理,可为类似工程提供参考。
Based on the actual situation of Miaojiaba hydropower station,the scheme based on measur⁃ing robot and supplemented by GNSS is adopted to replace manual measurement,and the intelligent ac⁃quisition and analysis system for dam deformation monitoring is developed.The exploration and practice are carried out from the aspects of observation method,measurement result correction and instrument protection.The intelligent 3D deformation monitoring system with typical characteristics of self-optimi⁃zation in observation period and self-protection of precision instrument is formed,which has capability for all-weather and all-time automatic monitoring.The intelligent monitoring of external deformation and real-time data processing is realized,worth reference for similar projects.
