| Abstract: | The excavation and design of the high tunnel are simulated by using ANSYS. By using the 2D-FEM of elastic-plasticity simulation of tunnel excavation is carried out, and the internal force of the lining is analyzed and calculated to inspect structure security, and the safety coefficient of the lining is calculated according to the equation of limit state. Then the thesis discusses the effect of thickness changing on lining safety coefficient and structure stability, thus offers guidance and reference for the design and construction of similar highway tunnel. |
