| Abstract: | The tunnel under the karst-fractured ground will rock the entire stress redistribution have a greater impact.By using finite element program on top of the tunnel there is a road tunnel cave rock stability,a series of numerical simulations to explore the size and location of the cave tunnel at the top of the stability of the surrounding rock,come to some of the empirical relationship. |
