摘要:: 铁路隧道进度与成本控制的目的是运用科学有效的措施方法,与工程实际相结合,合理制定施组计划,优化配置人员、设备,提高施工效率,提升进度,多层次、多方位降低各项工程费用支出,实现经济效益最大化。本文以新建某铁路隧道工程为例,从分部分项工程费、措施项目费两方面对施工成本进行分析,计算得出各级围岩最小工效指标E₁,通过现场测算实际工效指标E₂,计算得出各级围岩每月实际指标差,从施工进度管理的角度查找项目成本管理的关键要素。以进度就是最大的成本为主线,管住进度就是降低成本,降低成本才能提高效益,形成良性循环。

Abstract:: The progress and cost control for railway tunnels is meant to make a reasonable construction plan by optimizing the allocation of personnel and equipment with scientific and effective measures and methods based on the actual situation of the project, so as to improve the construction efficiency and progress, cut down various expenditures at multiple levels and in multiple aspects for maximum economic benefits. Taking a new railway tunnel as the case for study, the paper analyzed the construction cost from the perspectives of the divisional/subdivisional works and the measures taken for the project, calculated the minimum efficiency indicator E1 for different rocks, and calculated the actual monthly difference of the measured efficiency indicator E_</i>2 for different rocks to E_</i>1, to find the key factors to the project cost management from the perspective of construction progress management. The results show that the project progress is the key factor to cost, and cutting down the cost means making the progress under control, which is the only way to higher efficiency and a virtuous circle.
