摘要
以北京铁路地下直径线盾构隧道施工为例,介绍了不同工程地质及施工边界条件变化时的工艺参数选择原则,并通过对工艺参数调整时的施工效率、机具材料消耗统计,分析了成本的差异及变化。
Taking the underground diameter shield construction of Beijing railway for example, the choosing principles of process parameters in different engineering geo-conditions and changing boundary conditions were introduced. The cost difference and change were analyzed according to the analysis of construction efficiency and machine material consuming when the process parameters were adjusted.
