| Abstract: | This paper simulated the relationships between stress and strain for an excavated highway slope with traditional mechanical methods and unloading rock mass mechanics methods.Then it compared the slope displacements with the two methods,and it also did comparative analysis with monitoring data.The results testified the rationality about unloading rock mass mechanics methods in calculation and analysis for excavated slope of rock and soil mass. |
