Beijing is one of the most serious areas suffered from land subsidence in China. A series of environmental geological problems, such as the elevation loss caused by ground subsidence, have become one of the important factors that affect the urban planning and construction of Beijing and the sustainable development of regional economy. In recent years, land subsidence in Beijing is still at a rapid development stage. In addition to the groundwater over-exploitation, the scale of urban construction becomes a factor for the ground subsidence. The engineering-environmental effects of multilayer, high-rise buildings have more obvious effect on the ground subsidence. It is very important to analyze the relationship between the building load and ground subsidence. This work would be beneficial to the reasonable planning of buildings, to the predicting and analyzing of the ground subsidence, and to the reduction the hidden danger caused by ground subsidence.The Floor Area Ratio is an important index to measure the land use intensity, and it can reflect the building load. In this paper, the Floor Area Ratio index is used as a direct index to reflect the building load on the surface. The new index is extracted using the building shadow information on the GeoEye-2 images. By establishing a relationship among the shadows, building height and building load, the index can be calculated. The subsidence data can be obtained with InSAR(Interferometric Synthetic Aperture Radar) technique. The ...
