摘　　要：隧道工程涉及的围岩级别不同,其预算指标浮动较大,文中以福州市工业北路延伸线工程(第1标段)——文林山隧道工程为案例,深入分析案例涉及的各级围岩预算指标差异,并通过细化石方开挖、施工辅助措施、临时支护等预算指标,挖掘各级围岩预算指标产生差异的原因,以便从源头主动控制隧道工程的预算,以期为隧道工程设计优化与科学决策提供参考借鉴。Tunnel engineering involves different levels of surrounding rock,and its cost index fluctuates greatly.By taking Fuzhou Gongye North Road Extension Project(Section 1)-Wenlinshan Tunnel project as a case,the differences of surrounding rock cost index at all levels involved in the case are analyzed in depth and detail,and the cost index such as stone excavation,construction auxiliary measures and temporary support is refined.In order to control the cost of tunnel engineering actively from the source,the cause of the difference in the cost index of surrounding rock at all levels is explored,in order to provide practical guidance for the optimization of tunnel engineering design and scientific decision-making.
