| Abstract: | A three-dimension model of the tunnel is established by using self-developed GeoSMA-3D program,which can search the key blocks induced by tunnel excavation.The establishment of model for Lijiaying tunnel is depended on the discontinuous characteristics of its surrounding rock and based on the field investigation results of rocks’ structural plane and information collection.The three-dimension model is led into DDA which is a discontinuous deformation analysis method and the calculation analysis during tunnel excavation is carried out,at the same time,the time-history analysis during collapsed damage procedure without engineering measures is simulated.This project bears reference significance to timely treatment of project and key section. |
