| 摘 要： | 针对湖北鸦来公路沙子垭隧道在不同施工方法下围岩和隧道支护结构的力学问题,运用有限元的方法对双侧壁导洞开挖法和台阶开挖法进行了动态数值模拟,建立了在不同施工工序下围岩的应力场、位移场,并对这2种施工方法进行了比较,得出采用台阶法开挖的方案较优。 |

| Abstract: | Based on the Shaziya tunnel engineering of the Yalai highway in Hubei province,the mechanics problem of the surrounding rock and the supporting with different construction methods are studied.The excavating procedure of twin side heading and benching tunneling has been simulated numerically by the finite element method(FEM).The field of stress and displacement in the surrounding rock is suggested under the different order of the construction.By comparison of the two methods,the scheme of benching tunneling is much better than that of the twin side heading. |
| Keywords: | highway tunnel FEM twin side heading benching tunneling |
