呼图壁地下储气库GNSS连续站一致性分析

CONSISTENCY ANALYSIS OF GNSS CONTINUOUS POSITION IN HUTUBI UNDERGROUND GAS STORAGE

利用新疆呼图壁地下储气库内外的3个GNSS连续站一年的观测资料分析库区内部2个连续站的一致性及其与呼图壁M_S6. 2地震的关系。研究表明:储气库库区内部2个GNSS连续站的位置时间序列和基线时间序列均显示出较好的一致性,站点稳定,可以做为基准点。由于距离12月8日呼图壁M_S6. 2地震较远,地下储气库库区的2个连续站震前未能有明显形变异常反映,同震效应较小,震后有小幅的波动变化。

The consistency of two GNSS continuous stations in the reservoir and its relationship with Hutubi earthquake with Ms 6.2 were analyzed by using one year data of three GNSS continuous stations around Hutubi underground gas storage. Results showed that the consistency of position time series and baseline time series of two GNSS continuous stations were obvious, its stable to be refer- ence site. And the deformation and co-seismic effect of two GNSS continuous stations in the reservoir which caused by Hutubi earthquake with Ms 6.2 were small because of the long distance.
