摘要
It is stable in which the regional crustal environment is around Yangjiao town in Wulong County of Chongqing Municipality.The large slope in the back hill of Yangjiao town is not a integrated in historical rockfalls and landslide process,not to be of conditions in sliding deeply and no unitive in whole,but it is existent in which occur creepages,slippages and little landslides partly caused by lasting raining.Yunzishan in southern end of the slope is a residual peak what results from a monoclinal mountain eroded in geological process,but not bedrock sliding,rockmass movement or fractured rockmass induced by its self-sliding.Geo-hazards in Yangjiao town are mainly hazardous rockmass cracks,deformations and rockfalls induced by mined out area which are derive from long period of exploitation for coal or sulfur and iron ores along southern high cliffs.At present,many little scale of rockfalls often occur,but a large rockmass movement would not happen unless keep on mining,strong earthquake or intense rainstorm.So,the right countermeasures for geological safety to Yangjiao town would include stop mining under cliff of southern mountain,clean up hazardous rockmass,reinforce Yunzi peak,evacuate resident,implement early warning on geo-hazards,prohibit new engineering construction and put in risk managements.
