| Abstract: | In order to keep side slope of the super highway stable in the whole line during the excavation of this slope,Using finite difference method numerical analysis software FLAC 5.00,the stability of this slope of cut in its initial condition is simulated and analyzed.The program of prestressed anchorage strengthening is determined.The excavation and strengthening courses dynamically is simulated and analyzed.The results show that the strengthening are scientifically and reasonable. |
