摘要
介绍了静力水准系统(hydrostatic leveling system,HLS)的测量原理以及固体潮对HLS测量精度的影响,并对HLS数据进行固体潮调和分析,获得了该地区高精度的倾斜固体潮参数及模型。在此基础上,利用该地潮汐模型对HLS监测数据进行潮汐改正,进而得出当地两监测点之间的实际地面形变,为静力水准系统在高精度(μm量级)加速器准直测量中的应用奠定基础。
The measuring principle of hydrostatic leveling system and the tidal effects on measurement accuracy of HLS is introduced in this paper,and harmonic analysis of the tilt tidal observations based on HLS is completed.High-accuracy tilt tidal model and parameters are obtained afterwards.And the tidal correction of the HLS data based on local tidal model is completed,thus the actual ground deformation is obtained,the current research establish a foundation for HLS application in high accuracy alignment of particle accelerator.
