The three-dimensional model is used to interpret the earthquake damage on buildings in the mega-earthquake area in order to acquire different-level house damage in the Kuzirun village disaster area. In addition,the characteristics of seismic damage on typical buildings are analyzed. The results show that the main collapsed houses in the mega-earthquake area are sand-stone buildings,of which about 39% are sand-stone buildings. Several brick-wood buildings and brick-concrete buildings are seriously damaged,while the buildings with frame structures are mainly slightly damaged,and the houses near the macro-epicenter of the earthquake are all in good conditions. Three-dimensional tilt photography technology can vividly display the scene of earthquake disaster,and can provide significant demonstration in building damage degree together with detailed analysis of disaster situation.展开更多
