Abstract

By using the 2D-FEM of elastic-plasticity,simulation of tunnel excavation is carried out,and the internal force and safety coefficient of the lining is calculated to inspect structure security.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.
