摘要
Abstract
The physical parameters of homogeneous surrounding rock are relatively uniform in space,and their mechanical responses are predictable.In contrast,heterogeneous surrounding rock exhibits spatial randomness in mechanical parameters such as elastic modulus and cohesion,which directly affect rock failure behavior and mechanical properties.In addition,the choice of lining materials significantly influences tunnel stability and safety during both construction and operation.Taking a water conveyance tunnel project of a reservoir as a case study,finite element simulations were conducted using ANSYS to analyze and compare the stability of tunnels with reinforced concrete lining and steel lining under heterogeneous surrounding rock conditions.The results show that reinforced concrete lining exhibits better adaptability and stability in heterogeneous surrounding rock environments.关键词
