Abstract	Monitoring and governing the regional land subsidence along the highway and other linear projects has become an important basic work for the normal construction and operation in these regions. In this paper, by using the method of multi-track PS-InSAR integration, the land subsidence velocity varying with time along the JingHu highway (Beijing-Hebei) was studied with adjacent orbits ENVISAT ASAR data from 2008 to 2010. At the same time, the map of subsidence velocity along the highway was successfully extracted as well as the subsidence profile map. And 9 subsidence centers were verified along the highway according to these maps, which were consistent with the previous study. The results showed that the method not only unified the coordinate system of adjacent tracks, but also made cross-track, multi-image, large-scale PS-InSAR monitoring possible. Therefore, PS-InSAR monitoring results could provide a scientific reference for the subsidence control of highway and other linear projects, and protect the safe operation of the linear projects.
