摘　　要：针对河北涉县地磁台在2013年建设期间土体外运产生的载荷变化对水管倾斜仪观测数据影响进行了ANSYS有限元三维载荷模型分析。根据已知岩层特性把模型分成土体和岩石两部分,按照地磁台站建设施工前后的外运土体形状、规模分别构建模型,并结合动土期间水管倾斜仪运行资料进行分析,得出涉县地磁台站建设产生的载荷变化并未对水管倾斜仪观测数据产生明显影响。In this paper,we analyze the influence of soil load changes on the observation data of water pipe tipper during the construction of Shexian geomagnetic station in Hebei province in 2013 using ANSYS finite element three-dimensional load model.The model is composed of soil and rock,and is constructed according to the shape and scale of soil transported before and after the construction of geomagnetic station.The results show that the load variation caused by the construction of Shexian geomagnetic station has no obvious influence on the observation data of water pipe tipper.
