摘要
采用一种接触磨擦单元并利用广泛应用于岩土工程分析的 Mohr- Coulomb塑性准则对同一隧道采用不同的衬砌类型的结构性能进行了比较分析 。
Authors focus on a comparison of the advantages and disadvantages of a single and a double lining structure, which are both based on the same engineering background. The Mohr Coulomb plastic criterion is used to justify the plasticity of soil, and an effective and efficient contact interface element is employed to simulate the friction and contact case between soil and shotcrete or between inner and outer lining in the case of a double lining system.Some important results, such as the decoupling cases of the lining systems and the relevant distribution of the plastic zone as well as the lining forces, are obtained.
