| 摘 要： | 分析2011—2016年河北邯郸涉县台垂直摆仪器运行情况并计算其内精度，用质点、二维、三维载荷模型计算仪器周边工程建设载荷变化对垂直摆的影响，结果表明载荷变化对垂直摆数据影响不显著，二维载荷与三维载荷模型结果趋于一致，并得出动土时段可造成垂直摆内精度变差。

| Abstract: | In this paper, the operation of the vertical pendulum instrument at Shexian station in Handan City, Hubei Province, from 2011 to 2016 was analyzed, and the internal accuracy was calculated. The effects of load changes of surrounding project construction on the vertical pendulum were calculated by using the particle, two-dimensional, and three-dimensional load models. The results showed that the load change has no significant effect on the data of vertical pendulum at Shexian station. The results of two-dimensional and three-dimensional load models tend to be consistent. It is concluded that the inner accuracy of the vertical pendulum becomes bad during the period of ground breaking. |
