摘要
在系统清理重庆台十多年来的水平摆倾斜仪的记录图纸、观测数据与原始手簿后,分析总结了温度、降雨、抽水、载荷改变等强干扰的形态特征、干扰机理、影响量级等,确定了其识别方法和轨迹运行规律及排除方法;并对发生于距台站北67 km的统景5.4级地震(1989-11-20)前4天台站水平摆倾斜潮汐形变记录出现的异常现象作出了确属震兆异常图像的识别。
The observations of the horizonal penbulum tihmeter at Chongqing station since over 10 years before are arranged systematically. The feature, mechanism and magnitude of disturbance of temperature, rainfall, dewatering and loading variation are analyzed and summerized. The acting law of disturbance, the recoginition and elimination methods are determined. The anormalies recorded by the horizontal pendulum tihmeter at Chongqing station on the 4^th day before the M5.4 earthquake（1989-11-20） occured in Tongjing about 67 km away from the station are recoginited as the earthquake precursor.
