| 摘 要： | 基于安丘地震台跨断层短水准、短基线和MD断层蠕变观测同期资料的变化特点、干扰特征,采用相关分析方法讨论了三者之间的关系.结果表明:1)安丘定点短水准观测受温度和地下水位的影响,与温度负相关,与地下水位正相关;安丘基线与温度显著相关,相关系数达0.95;MD断层蠕变观测水平正交、斜交和垂直观测均受温度影响,MD断层水平正交、斜交长期资料与温度相关性很好,相关系数分别为0.98和0.99,但短时间MD观测与温度相关性比较复杂,观测到的地表形变超前于温度变化;垂直观测分量在不同的季节,观测值与温度相关程度不同.2)短基线和MD断层水平正交一致性较好,在场地合适的情况下可进行对比观测;短水准和MD垂直观测分量没有明显的一致性变化特征,MD仪安装在半地下室的情况下,两者不适合进行同步观测.

| Abstract: | The varying characters of observations and disturbances of the cross fault short leveling,short baseline and MD fault creep testing apparatus at Anqiu seismic station are deseribed,and the relationship of above three methods using correlation analysis method is discussed.The results show that: the short leveling observations are affected by temperature and ground water level,and the observations are negatively correlated to temperature,positively correlated with ground water level.There is a obvious correla... |
