摘　　要：粒子加速器运行时,地面变形会导致束流畸变甚至丢失,所以在粒子加速器领域对地面变形进行研究很有必要。通过在合肥光源直线加速器隧道先后搭建两套并行分布、由7台间隔10 m的静力水准传感器构成的静力水准系统,经过对两套系统采集的共计三段为期半个月的监测数据进行分析,发现了ATL模型中存在的线性关系,分别得到不同时段本地区模型常数值,并发现了模型常数与季节温度的相关性。最后通过数据对比发现地面点相对运动中的周期成分主要受固体潮效应影响。For particle accelerators,ground deformation can cause beam distortion or even loss,thus it is necessary to study ground deformation in particle accelerator field.After constructing two parallelly distributed hydrostatic leveling systems consisting of 7 static leveling sensors spaced 10 m apart in the Hefei Light Source’s linear accelerator tunnel successively,we analyzed a total of three periods’monitoring data collected by the two systems for a period length of half a month.We found the linear relationship in the ATL model and obtained the constant values of the ATL model separately,and discover the correlation between the model constant and seasons’temperature.Finally,through data comparison,it was found that the periodic components in the relative motion of ground points were mainly affected by the Earth tide.
