| Abstract: | The hidden points of dangerous rocks distributed on the mountain in the northeast of Nongling,Penghuai Village,Tongde Town,Jingxi City.It was urgent to find out the geological environmental conditions,scale and stability of the development of dangerous rocks,and predict the development trend and hazard degree.The results showed that there were 4 dangerous rock bodies in the exploration area,whose total volume was 697.3 m3,which belonged to small high dangerous rock mass.The macro stability of dangerous rocks was poor.It was easy to collapse under the impact of weathering,rainfall,vibration,plant root growth to break rock and other factors.The rock mass was basically stable to unstable under rainstorm,and there was the possibility of collapse and instability.The geological disaster of dangerous rock collapse threatened the safety of lives and property of people living at the foot of the mountain slope. |
