| Abstract: | According to popular guide line of Drucker-Prager for rock,based on Liuzhuling tunnel real engineering in Guangxi,by using finite element method,applying ANSYS software,building two-dimensional model,simulating the influence of karst cave that parallel to the tunnel in different locations on the tunnel surrounding rock stability.Some useful conclusions have been drawn,could provide some reference to the construction,design and research of tunnel in southwest karst area. |
