| 摘 要： | 从年变形态、主要干扰、震前异常特征方面对同车公司地裂缝的水准观测进行综合分析，结果表明，地裂缝的总活动趋势是以垂直方向的沉降活动为主，地裂缝活动与地震活动有较明显的相关性。震中距在300km范围内的M5以上地震，震前异常表现形态较多，变化幅度较为明显。M4．5以下地震可能存在的前兆异常和干扰无法区分，不易识别。

| Abstract: | Deformation level observation for ground fissures at Datong Tong Train Co. is comprehensive analyzed from aspects of annual vari- ation, main interference, anomalies before earthquakes. The results show that the overall activity trend of ground fissures is mainly vertical settlement and ground fissure movement obviously is correlated to seismic activity. For earthquakes larger than M5 and with epicentral dis- tances within 300 km, there are noticeable abnormal variations before earthquakes. Whereas for earthquakes smaller than M4.5, precursory anomalies and interference can not be distinguished and can not be easily to identified. |
