摘　　要：随着国民经济的发展,我国中西部地区铁路建设速度加快,由于地形原因,建设的长大隧道越来越多。对含辅助坑道的长大隧道施工,依据铁建设"[2010]223号定额"和"[2012]129号定额",是按划分的工区编制概算,还是按隧道全长编制概算,此文根据隧道施工过程和工序以及采用的定额,从隧道开挖、出砟、通风管线路、混凝土和材料运输等方面,结合工程实例,对比分析断面≤90m^2的隧道和断面>90m^2采用机械化施工的隧道,是按工区编制概算还是按隧道全长编制概算合理。经对比分析表明,按工区编制概算符合实际隧道工程造价情况,比较合理。With the development of national economy, the railway construction in the central and western regions of China speeds up. Due to the terrain, the construction of the long and large tunnel is increasing. For the long and large tunnel contains auxiliary tunnel, the budget preparation is according to division of work ar- ea or tunnel length need be researched. In this article, according to the tunnel construction process and the working procedure and the quota, from the aspects on tunnel excavation, a frantic jumble, ventilation route of pipelines, concrete and material transportation, etc. , combined with the engineering example, the two budget preparation methods are compared in view of the tunnel with section ≤90 m2 and the sec- tion 〉 90 m2. The comparative analysis shows that, the budget preparation according to work area is more reasonable than that according to the tunnel length.
