摘要
在众多隧道开挖方法中,台阶开挖法在一定时期内仍将是我国隧道施工的主流方法.通过数值模拟的方法,对比分析了不同台阶长度对于隧道的影响.在对比了3种不同的台阶长度方案后,最终确定3种方案中5 m台阶长度最符合工程需要.试验结论适用于类似隧道工程,具有一定的实际应用价值.
Among many methods of tunnel excavation, the step excavation method is always dominant in the tunnel construction in China. This paper comparatively analyzes the influence of the different steps on the tunnel through numerical simulation. By comparing three different bench length schemes, the length of the 5 m level was considered the most proper one satisfying the needs of the project. The experiment conclusion is practical and ap- plicable to the similar tunnel construction.
