摘　　要：西影井水位自1974—1978年三次井溢后,1989年9月以来又出现了一次大起大落的特异变化。很多学者都十分关注这罕见的现象,并认为是区域应力增强所致的。经过多年的调查与分析,笔者认为是大量抽取地下水引起的地面沉降与地裂并由此导致地下岩层的层间错动与井管变形破坏的结果。After three times well overflow during 1974-1978, Xiying well water level has appeared anomalous variation once. Many scholars pay close attention to this rare phenomena, and think it is caused by enhance of tectonic stress. After many years investigate and analysis, author considered that it is caused by ground subsidence and tafroge-nesis after draw a large amount of underground water and caused interformational dis-turbunce of rock stratum and deformation destroy of borepipe.
