摘要
研究目的:工程定额是合理确定工程造价、有效控制工程投资的重要基础。铁路工程建设规模越大、标准越高,投资规模也就越大,加强投资控制,节约来之不易的建设资金也就愈发重要[1]。对于项目投资控制和管理工作者而言,准确选择与设计意图相匹配,与施工组织方案有机结合的定额编制预算意义重大。目前铁路行业隧道工程预算编制主要存在有三种类型定额,本文旨在通过对比分析,为断面有效面积90 m2左右铁路隧道的定额类型选择和造价确定提供帮助。研究结论:(1)从隧道开挖、出砟、二衬圬工、混凝土运输等方面综合分析,同一断面形式下,高铁定额造价水平高于普通定额;(2)从隧道断面引起的作业工况、工机损耗等角度,考虑不同部位施工难度差异、长隧道的特殊性等,高铁定额造价水平更接近现场实际;(3)该研究成果可用于把握定额内涵并确定工程造价、编制完善企业施工定额等。
Research purposes： Engineering quota is an important foundation to the reasonable determination of engineering cost and the effective control of project investment. Nowadays the scale of railway engineering becomes larger and the standard gets higher, so the cost of project increases. Hence, strengthening the control of investment and economize the construction funds is becoming more essential. The exact choice of quota in budget presentation that matches the design intent and construction organization scheme is very important to the investment control manager. Currently, there are generally three types of quota in railway tunnel project. In this paper, comparative analysis was performed for the determination of cost and the selection of quota type of the railway tunnel with a 90 m^2 effective area section.Research conclusions： （ 1 ） Comprehensive analysis based on tunnel excavation, mucking debris from tunnels, secondary lining, concrete transportation and other aspects showed that the cost of tunnel with same section on the high - speed railway quota is higher than the cost on general railway quota. （2） Considering with construction difficulties in different position of the tunnel and the particularity of long tunnel from the working condition, manpower, mechanical loss and others, the cost on the high - speed railway quota was in accordance with the facts. （3） The achievements can contribute to determine project cost and perfect the construction quota of enterprises by expounding the connotation of quota.
