| 摘 要： | 为了研究聚丙烯纤维混凝土锚喷结构的力学性能，采用ADINA大型非线性有限元分析软件，对沪汉蓉通道老安隧道的锚喷衬砌支护进行受力模拟分析，与使用普通混凝土进行了比较。结果表明，该支护结构有效改善了围岩的应力分布，且裂缝减小，承受荷载增加，明显优越于普通混凝土。

| Abstract: | In order to study mechanical property of anchoring and shotcreting, nonlinear finite element analyses software ADINA is used to simulation stress distribution of lining timbering shorting of Laoan tunnel and compared to the situation with plain concrete. The results presented that wall rock stress distribution was improved availability, crack minish and load enhanced. This structure with polypropylene fiber concrete is superior to that with plain concrete. |
