摘要
针对姑咱台SQ石英摆倾斜仪测值从2002年9月开始出现大幅度异常变化,四川省地震局先后3次派出工作组进行了现场落实。通过对仪器运行状态、观测环境状况和观测人员工作过程进行仔细调查,经对比分析后认为:该异常是由于环境干扰所致,不属于地震前兆异常。
Precursory data of the tilt meter SQ appeared from September 2002. To ensure whether or not there are interfere factors, three times investigating in the spots were made. The tilt meter running state, the observing environment and the personal maintaining level are carefully studied. We found the high way construction is main factor to interfere the data of tilt meter.
