摘要
用VAV03和TSoft软件对深圳黄贝岭断层垂直形变资料进行了调和分析,并对宜昌DZW重力仪数据潮汐因子的变化进行了计算,结果表明:黄贝岭断层各波段的潮汐因子偏小,说明断层对潮汐波有缩小作用;宜昌台潮汐因子存在异常变化,这些变化大部分是数据异常造成的。通过最小二乘法对观测数据进行潮汐分析,证明VAV03对形变和重力数据的潮汐分析是通用的。
The harmonic analysis of vertical deformation data of Shenzhen Huangbeiling fault is carried out and the tidal factor variation of Yichang DZW gravimeter dada is calculated. The results of Huangbeiling data show that the tidal factors of each wave band are relatively small because of the fault activity which conforms to the universal law that the tidal wave are global and the fault activity are local. The results of Yichang data shows that there exists abnormal tidal factor changes which overall results from data anomaly. The Huangbeiling and the Yichang results show together that the VAV03 program is applicable in both gravity and deformation tidal analysis.
