摘要
以具体工程为例,介绍了三台阶临时仰拱法在单线铁路隧道中的应用,分别阐述了CRD法与三台阶临时抑拱法的优缺点,并对开挖方案进行了优化,实践证明采用三台阶临时仰拱法施工既可保证隧道安全又能提高施工工效。
Taking factual projects as the examples,the paper introduces the application of the three-step temporary invert method in single-line railway tunnels,illustrates the advantages and disadvantages of CRD method and the three-step temporary invert method,optimizes the excavation scheme,and proves the three-step temporary invert method can not only ensure the safety of tunnel,but also improve the construction efficiency.
