摘　　要：以河北文安5.5级地震为例,分析了地震前天津地区流体测项的异常变化。结果表明,天津王3井、王4井水汞、潘庄井及双桥1井水位在震前都出现了明显的短期前兆异常。Taking the earthquake of ML5. 5 of Wenan, Tianjin, as an example, abnormal variation appeared in fluid observation in Tianjin region before the shock is analyzed. The result shows that obvious short-term precursor anomalies occurred in wells of Wang No. 3, mercuric gas in water and water levels in Panzhuang and Hangushuangqiao wells in Tianjin before the earthquake.
