| 摘 要： | 抽水所造成的地下水位的变化会即时在局部范围内造成地表的形变，干扰定点地壳形变观测。在蓟县地震台进行的抽水实验表明：这种干扰的幅度与抽水水井到形变监测仪器的距离有关，也和抽水水井水位的最大降深有关。根据实验数据得到了抽水对定点形变观测的影响范围的经验公式。 |

| Abstract: | An experiment was carried out at the Jixian station in Tianjin to explore the disturbance arising from the dynamic groundwater level to the crustal deformation observation. It demonstrated that the change of the groundwater level caused by the water withdrawal will lead to ground deformation in the local region at once and disturb the crustal deformation observation. The disturbance is related to the distance between the well and the deformation instrument. And it also has some relation with the maximum drop of the well water level. On the basis of the data collected, a formula can be derived for estimating the influence range of pumping groundwater on the deformation observation. |
