| 摘 要： | 为了确保城市轨道交通的安全运营和可持续发展,将高分辨率PS-InSAR技术引入城市轨道交通的形变监测领域。以上海为例,分析了城市轨道交通网络专题的形变特征。首先,利用26景TerraSAR-X影像在上海开展高分辨率PS-InSAR沉降精细测量,得到轨道交通网络整体的沉降格局;然后,针对不同建成时期和建设形式的路段,分类探讨其形变特性及原因;最后,进行测量结果的精度验证。分析结果表明,快速的城市化发展建设已成为上海轨道交通沿线主要的沉降原因;不同建成时期和建设形式的路段表现出不同的形变特征,早期建设路段比晚期建设路段更稳定,高架路段比地下路段沉降速率更小;PS-InSAR与水准数据保持很好的一致性。证实了高分辨率PS-InSAR技术在城市轨道交通形变监测、管理维护和预警方面具有一定的可行性,可以为城市公共交通的规划和建设提供决策支持。通形变监测、管理维护和预警方面具有一定的可行性,可以为城市公共交通的规划和建设提供决策支持。

| Abstract: | In order to make sure the security and sustainable development of the urban rail transit, the PS-InSAR technology is introduced into the deformation monitoring of urban rail transit. Taking Shanghai as an example, it is analyzed that the characteristics of surface deformation along the rail transit. Firstly, 26 TerraSAR-X images are used to carry out the high-resolution PS-InSAR subsidence fine measurements in Shanghai for the overall land subsiding characteristics of rail transit. Then, the detail subsidence pattern and the driving force is discussed by classified the rail transit with different construction periods and building modes. Finally, the accuracy of the results is verified by leveling in the same period. The results show that rapid urbanization construction has become a main reason for the subsidence of Shanghai rail transit. Rail transit with different construction periods and building modes show various deformation characteristics. Earlier sections are more stable than later sections and elevated sections have smaller subsidence rate than underground sections. The verification results show fairly consistent agreement. The results further illustrate that it is feasible to use the high-resolution PS-InSAR technology into the deformation monitoring, management, maintenance and early warning of urban public transportation projects. It can also provide decision support for planning and construction of urban public transportation. |
