| 摘 要： | 对武汉基准地震台倾斜固体潮观测资料的研究表明,固体潮曲线畸变是降雨渗透使基岩膨胀的结果。降雨对记录曲线的影响主要表现在:1)时间上具有同步效应。降雨发生后倾斜仪的NS分量发生南倾,EW分量发生东倾;2)量级上受降雨干扰严重的主要为NS分量,EW分量受干扰程度较轻;3)垂直摆受降雨的干扰程度比水管仪的大。

| Abstract: | The disturbance patterns of the tiltmeter observation of VS and DSQ at Wuhan station during the period of Tenth Five Year Project were studied.It is found that the rainfall and other factors may have the serious effect on the tide distortions.By analyzing the abnormal phenomena of the tilt tide curves,it seems that above anomalies arised from rainfall osmosis bringing about the expansion of base rock.It can be seen that there is a close correlation between the tile tide aberration and rainfall.The disturban... |
