| Abstract: | In the light of the development and limitations in macro mechanical parameter selection and determination method at present,and based on the mechanical parameters of intact rock mass and fractured structure plane obtained indoor rock mechanical test,we conduct a numerical simulation and analysis on fractured rock mass at the dam site of Rumei Hydropower Station on Lancang River in Tibet by equivalent calculation method,and obtain ther equivalent influential factors to the parameters of fractured rock mass.A new method for 3D digital simulation and analysis on macro mechanical parameters of fractured rock mass is suggested. |
