为了查明油气重大基础设施中，由星载雷达干涉测量、地面全球导航定位系统（global navigation satellite system, GNSS）形变监测、地下位移传感器监测和管道应力应变监测网络构成的星地一体化监测技术的有效性，采用SBAS-InSAR技术提取了天津LNG（liquefied natural gas）码头区域油气管线区域的长时间序列的地表形变数据，进一步分析了地面GNSS地表位移、多层深度位移计、管道应变传感器数据与同步的SBAS-InSAR地表形变量的数据响应关系，并进一步分析了雨-旱循环的时序变化规律。结果表明：2019-05—2022-04月的3年间天津LNG码头区域非均匀沉降最为显著，最高达到-394 mm；SBAS-InSAR的时序形变数据15 ~ 53 mm的沉降形变，在GNSS中有9 ~ 57 mm的地表位移响应，两者相关显著，具有良好的一致性；SBAS-InSAR地表形变变化特征与多层位移计在1、2、3 m深的位移数据响应特征都与降水量关系密切，呈现显著的雨季-旱季波动特征，二者具有良好的同步性，说明SBAS-InSAR地表形变变化特征能够揭示地下土层的位移变化特征；SBAS-In-SAR地表沉降量与地下管道应变呈正相关，SBAS-InSAR获取的地表形变是反映地下管线应变的良好指标。由星载雷达干涉测量、地面GNSS形变监测、地下位移传感器监测和管道应力应变监测网络构成的星地一体化监测数据的集成应用，能够为未来星地一体化的管道安全监测技术体系构建提供有益的借鉴。

In order to investigate the effectiveness of an integrated space-ground monitoring technology that consists of spaceborne radar interferometry, global navigation and positioning system (GNSS) deformation monitoring, underground displacement sensor monitoring, and pipeline stress-strain monitoring in major oil and gas infrastructure SBAS-InSAR technology to extract long-term surface deformation data in the Tianjin LNG (liquefied natural gas) terminal area was employed. Additionally, the relationship between ground GNSS surface displacement, multi-depth displacement meters, pipeline strain sensor data, and synchronous SBAS-InSAR surface deformation data was examined. Furthermore, the temporal variation patterns of rainfall-drought cycles was analyzed. The findings of this study indicate that the non-uniform settlement in the Tianjin LNG terminal area was most significant over the three-year period from May 2019 to April 2022, with a maximum value of -394 mm. Analysis of the temporal deformation data derived from SBAS-InSAR revealed subsidence deformation ranging from 15 ~ 53 mm, while ground displacement measured by GNSS exhibited responses ranging from 9 ~ 57 mm. There was a strong correlation and consistency between the two measurements. The changes in SBAS-InSAR surface deformation were closely linked to precipitation, as observed by multi-depth displacement meters at depths of 1 m, 2 m, and 3 m. These changes demonstrated significant fluctuations between the rainy and dry seasons, exhibiting good synchronization. This suggests that the characteristics of SBAS-InSAR surface deformation can effectively depict the displacement patterns of underground soil layers. Additionally, the surface subsidence measured by SBAS-InSAR showed a positive correlation with underground pipeline strain, indicating that SBAS-InSAR surface deformation data serve as a reliable indicator for assessing the strain in underground pipelines. The integrated application of spaceborne radar interferometry, ground-based GNSS deformation monitoring, underground displacement sensor monitoring, and pipeline stress-strain monitoring in a space-ground integrated monitoring system can provide valuable insights for the future development of pipeline safety monitoring technologies.
