| Abstract: | Taking the underground excavation of certain water conservancy project as an example,two equations for the stability evaluation of the arch and the two sides of the underground excavation in low ground stress regions have been gotten by using block theory.Through the analysis and calculation it is indicated that the two equations for the stability evaluation are correct and efficient,which is significant to the further study of the stability evaluation of underground excavation. |
