| 摘 要： | 以基岩GNSS连续观测站为背景，考察各土层GNSS连续观测站垂直、水平分量的变化特征。观测结果表明，排除沉降干扰，严重沉降站一般需要改正，一般沉降站视研究需要决定是否改正。最后给出受沉降影响的测项的改正方法。

| Abstract: | In this paper, we take rock-based GNSS continuous stations as referents, and inspect the observed deformation variations in both horizontal and vertical components of every soil-based GNSS continuous station. Observations show that severe subsidence stations must be corrected, slight subsidence stations should be corrected depending on the research goals, and no correction is needed on non-subsidence stations for continuous GPS observations. We also present some methods for subsidence correction on GNSS station observations. |
