摘要
利用ANSYS有限元分析软件,对某公路隧道的设计与开挖过程进行了仿真分析。采用二维弹塑性有限元分析方法,对衬砌结构的内力进行计算和分析。并结合公路隧道设计规范给定的极限状态方程,计算出隧道衬砌的强度安全系数。研究衬砌厚度变化对其安全系数和结构稳定性的影响,为类似隧道设计施工提供科学依据。
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.
