| Abstract: | Building vulnerability evaluation is important in the risk assessment on earthquake and flood hazards. But for landslide hazard,
it is also a very important part for the people in buildings. Most discussions or researches about building vulnerability
are for landslide failure, few for landslide in deformation phase. For this objective, this paper discussed about building
vulnerability evaluation using Zhaoshuling landslide as an example Zhaoshuling landslide named located in the Three Gorges
Reservoir Area, China. After a field survey on the geological condition of landslide, detailed field investigation on the
buildings’ location and structure is carried out. To get landslide surface deformation, numerical simulation method is used
under the combining condition of water fluctuation and rainfall. Then building deformation and probable damage degree is analyzed
according to landslide surface deformation and the relative theory in mining. Based on the national standard building damage
classification system, the vulnerability of all the buildings on the landslide is semi-quantitatively evaluated. |
