摘要
随着面板堆石坝建设高度的逐渐增加,用于大坝变形监测的常规仪器不能完全满足需要。为此,提出了利用磁惯导系统进行大坝变形监测的方法,对磁惯导系统的具体组成、监测原理进行了阐述。将磁惯导系统用于水布垭大坝面板挠度的监测中,通过对其连续两次监测数据的处理和分析,以及磁惯导系统监测结果与光纤陀螺系统监测结果的对比,发现磁惯导系统监测数据可以较好地反映出大坝面板的变形趋势,证明了磁惯导系统用于大坝变形监测的可行性。
With the increasing height of the concrete face rockfill dams, the conventional instruments for dam deformation mo- nitoring cannot fully meet the actual demand. To this end, a monitoring method of dam deformation by magnetic inertial naviga- tion system is put forward, and the specific composition and monitoring principle are introduced. Then the magnetic inertial navi- gation system is applied to monitoring the slab deflection of Shuibuya Dam. Through two consecutive monitoring data analysis and the comparison of monitoring results between magnetic inertial navigation system and fiber optic gyro system, we find that the mo- nitoring data of magnetic inertial navigation system can better reflect the deformation trend of the dam slab, which proves the fea- sibility of magnetic inertial navigation system.
