Stability Analysis and Risk Zoning of Dongzhou District Government Site in Fushun City

Fushun has been known as the "coal city" for a long time. Since the founding of the nation, along with the rapid economic development of Fushun, coal resources development and utilization are also increasing gradually. Geological disasters such as the ground subsidence or collapse which caused by underground coal mining occurred frequently, destroying the ground buildings, making the construction crack, incline and even collapse; road occur cracks, scarps; destroying of underground pipeline facilities. And this constitutes a threat to people's life and property security. So before the production and construction, the field stability evaluating and risk zoning play very important roles. In this paper, Fushun Dongzhou District government area is taken as an example, through the investigation, to find out engineering geology condition of the site, analysis the type, cause of geological hazard and effects on buildings, putting forward preventive measures. Through the prediction of geological hazard prone zone, divide the ground collapse prone zone, ground unequal settlement prone zone, and stability zone.
