利用GPS技术研究山西跨断裂剖面垂直形变

Research on Vertical Deformation of Fault-crossing in Shanxi by GPS Technotogy

利用2009-2012年山西3个跨断裂综合剖面的GPS和水准资料，分别获取了这3个剖面的垂向形变速率。结果表明：在时间间隔较短（数月至1年左右）、观测时间不同步的情况下，GPS观测与水准观测获得的垂直形变速率偏差较大；在观测时间间隔较长（3年及以上）时，二者之间有较好的一致性，同时也验证了在较长时间尺度上利用GPS技术获取跨断裂综合剖面垂直形变的可行性。

After processing and computing the GPS data and precise leveling observation data of three comprehensive fault-crossing profiles from 2009 to 2012, we compared the obtained vertical deformation rate of these three pro- files. The results showed that when the observation time interval is shorter （from a few months to one year） and the observation time is not synchronized, the difference of vertical deformation rate between GPS and precise leveling observations are larger. When the observation time interval is longer （ for three years or more than three years）, the vertical deformation rate between them have good consistency, which verified the feasibility of ap- plication of GPS technology to the vertical deformation of fault-crossing comprehensive profiles in the longer time scale.
