【Abstract】 Geofractures have brought about serious hazard in Datong City. Because the geofractures have tectonic characters, it is resistless to damage buildings. How the precious soil resources are utilized? The most effective method is to adopt keeping a certain distance, i.g. safe distance. Based on the actual information of investigation on geofractures in Datong city over several years, the zonation of damage strength and determination of safe distance of buildings at geofracture site were studied using the synthetic method. Thus provide scientific basis for a reasonable use of geofracture site in Datong city.更多还原
