摘　　要：目前城市轨道交通工程明确区分了明挖隧道的有关费率,而铁路和市政工程并没有明确区分明挖隧道的有关费率,已不能满足大规模工程建设的需求。统计已建明挖隧道的工程费率表明,明挖法隧道具有材料费占造价比例大、定额人工费和定额机械费的占造价比例明显偏小的特点。结合既有规范条文规定,建议铁路明挖隧道施工造价参照《铁路基本建设工程设计概(预)算费用定额》类别代号为10的费率编制;市政明挖隧道施工造价建议参照城市轨道交通工程费率编制。Currently,urban rail transit projects have clear cost breakdown of open excavation tunnel,while railway and municipal engineering doesn′t have,which is insufficient to meet the demand of large-scale engineering construction.After analyzing the costs of completed open excavation tunnels,it is found that the proportion of materials is high,while the proportions of labor and machine costs are relatively low.Considering the terms of current code,it is suggested that the cost of railway open excavation tunnel should be handled according to the rate of Class 10 in the"Budgeting the Cost Quota of Basic Design for Railway Projects".The estimating method of municipal tunnel cost is suggested to operate in line with urban rail transit projects.
