Delft University of Technology Structural Health and Stability Assessment of High-Speed Railways via Thermal Dilation Mapping With Time-Series InSAR Analysis
Thermal dilation is a vital component of deformation along the extensive railway network infrastructure. To monitor subtle deformation, Synthetic Aperture Radar Interferometry (InSAR) technique has been adopted as a space-borne geodetic tool. However, InSAR applications in railway stability surveillance have been largely limited by the sparseness of detectable point-like targets (PTs). Moreover...
متن کاملStudy of subsidence of Abarkooh plain of Yazd using the Synthetic Aperture Radar Interferometry method
Abstract The population growth, the development of cities, industry, agriculture, and improper use of resources especially non-renewable resources have led human beings to face the danger of running out of resources. In some cases, in addition to the above, irreversible environmental and geological hazards have occurred due to the overdrawn of resources. Over extraction of groundwater resourc...
متن کاملUsing Permanent Scatterer Insar to Monitor Land Subsidence along High Speed Railway- the First Experiment in China
We present in this contribution the results of the first experiment to monitor land subsidence along JingJin High Speed Railway (JingJin HSR), which connects Beijing city and Tianjin city and is the first high speed railway in China, by using the Permanent Scatterer InSAR (PSI). Since the length of the railway is usually beyond the standard scenes coverage of the ongoing radar satellite, i.e. E...
متن کاملMonitoring of urban subway lines subsidence Using satellite radar interferometry method (Study area: Part of Tehran Metro Line 7)
Nowadays, satellite radar interferometry method plays an important role in calculating natural and artificial displacements, including displacements caused by floods, earthquakes, landslides, drilling of unauthorized wells, drilling of urban tunnels, etc. Metro tunneling is very important due to the importance of preventing irreparable financial and human losses. In Tehran, especially due to th...
متن کاملMonitoring of Subsidence along Jingjin Inter-City Railway with High-Resolution TerraSAR-X MT-InSAR Analysis
Synthetic Aperture Radar Interferometry (InSAR), widely applied for the monitoring of land subsidence, has the advantage of high accuracy and wide coverage. High-resolution SAR data offers a chance to reveal impressive details of large-scale man-made linear features (LMLFs) with Multi-temporal InSAR (MT-InSAR) analysis. Despite these advantages, research validating high-resolution MT-InSAR resu...
