摘　　要：水工混凝土配合比定额是水电工程概预算定额不可缺少的配套资料,混凝土配合比材料用量是直接影响混凝土单价的关键因素之一,进而影响工程投资。水工混凝土配合比定额研究的最终目的是为工程造价服务,研究成果不仅要方便造价专业人员使用,更重要的是要将设计意图如实反映在工程造价中。原水力发电建筑工程概算定额(1997版)附录中收录的"混凝土砂浆配合比及材料用量"(以下简称"97附录")已不能适应新技术规程和规范的要求,据此编制的工程单价与实际有一定偏差,为合理确定和有效控制工程造价,基于我国近10年已建或在建100余座水电站工程实际资料对流动性混凝土配合比定额进行研究,研究得出了287个配合比定额,并将研究成果与"97附录"进行对比,对比结果显示拌合物材料总费用较"97附录"基本呈降低趋势。该工作的开展不仅填补了这方面研究的空白,也为进一步研究水工混凝土配合比定额奠定基础。Hydraulic concrete quota is an indispensable supporting material for hydropower projects. It is one of the key factors that directly affects the unit price of concrete, which affects the investment of projects. The final aim of the quota research on the hydraulic concrete mix ratio is to serve the project costs. The research resuhs should not only be used by the professionals who make the cost, but also reflect the de- sign intention accurately in the project cost. 1997 edition Appendix of Concrete Mortar Mix and the Amount of Material can not meet the re- quirements of the new technical regulations and norms, which prepare the project unit price and the actual there is a certain deviation, for the reasonable determination of the original hydropower construction project. And 287 matching quotas were obtained and the resuhs were compared with the ＂97 appendix＂. The comparison results show that the total cost of the mixture material is lower than that of the ＂Appendix of 97＂. The development of this work has not only filled the gaps in this study, but also laid a foundation for a further study of hydraulic concrete mix quotas.
