摘　　要：2013年3月25日以来山西代县台水准测线出现的加速趋势变化是可信的,显示正断层活动。根据环境调查来看,也包含一定的干扰因素:(1)下午测量时经常风比较大,对测量结果会有一定影响,但该影响是随机的,应在基值附近波动,不应出现趋势变化;(2)BM3号点周围池台在2012年9—10月进行了维修,2013年又出现裂纹,说明该点周围的稳定性较差;另外,同期换记录程序只是数据记录方式的改变,不会对观测结果产生影响。The leveling measurements of acceleration tendency change at Daixian station since May 25th,2013 is credible,showing normal fault activity.According to environment investigation,it includes some interference factors.Due to the big wind during the leveling measurements in the afternoon,there is certain influence on the results,but the impact is random.The result fluctuates near the base value and does not show any trend change.The point BM3 was maintained during September and October,2012,and cracks appeared in 2013,indicating that the stability of point BM3 is poor.In addition,the change of recorded program only changed the way of data record and did not affect the observation results during the same period.
