摘　　要：本文应用构造分析的方法 ,对青岛胶州湾 3.2级地震发生的地震地质背景和构造背景进行分析。结果表明 :胶州湾 3.2级地震主要受 NEE向郝官庄断裂和 NNW向大沽河断裂控制 ,并根据现代活动断裂的标志 ,对上述By using the method of geologic structural analysis, the backgroung of seismic structure and the controlled earthquake faults of 3.2 grade earthquake in Jiaozhou Bay are studied. It is assumed that the earthquake was mainly controlled by the Haoguanzhuang fault and Daguhe fault which run in the NEE and NNW direction respectively. Based on the marks of modern movements of fractures, the characteristics of the two faults are expounded.
