摘　　要：甘１８井位于兰州市七里河区崔家崖大滩，于１９８２年起投入地震监测。本文介绍了该井１９８５－１９９３年期间的观测结果，分析了Ｍ＿２波潮汐因子和水位月均值的动态特征，讨论了黄河水位、降雨和气压对该井水位的可能影响。基于水位月均值残差曲线讨论了该井水位对景泰地震的前兆响应。The Can-18 well is the static water table well and is located at Qilihe district in Lanzhou of Gansu Province.In this paper,the observational results of the well during1985-1993 are introduced.The dynamic characteristics of M_2 wave and the monthlyaverage values of the water table of the well are analysed.The influence of Yellow Riverlevel and the rainfall and the air pressure near the well upon the results of the well arediscussed.Based on the residual curve of monthly,average values,the Jingtai Pre-earthquake anomaly is discussed.
