摘　　要：质量成本是工程质量水平的经济衡量指标,是保证工程质量、降低成本、提高收益以及判断质量体系有效性的重要工具。目前,碾压质量实时监控作为先进的技术手段运用到面板堆石坝施工中,其最大的优点是投资少、效益高。但现有研究都集中在实时监控系统对面板堆石坝质量水平的控制,对于实时监控系统的经济效益研究不多。针对上述问题,本文基于碾压质量实时监控系统,在阐述了质量水平与质量成本关系的基础上,明确了面板堆石坝施工过程的质量成本分析方法,构建了实时监控特征参数的质量成本预测模型,提出了施工过程质量成本的控制和改进的方法,对实时监控系统下的面板堆石坝施工做出了更加全面可靠的评价,为工程质量管理提供了科学的依据。Quality cost is an economic indicator of engineering quality level combining the safe reliability and the economical applicability. Quality cost management is an important tool for ensuring project quality,reducing cost,increasing revenues and judging the effectiveness of the quality system. As an advanced technology with low investment and high revenues,real-time compaction quality monitoring has been used for the construction of rock fill dam with face slab. But the existing researches focus on the control of the quality level and do not fully discuss the economic benefits of the real-time monitoring system. In the present study,the authors firstly analyze the relationship between the quality level and the quality cost based on the real-time compaction quality monitoring system. Second,the quality cost analysis method for the construction process of the rock fill dam with face slab is proposed. Then a quality cost prediction model based on the characteristic parameters of the real-time monitoring is built. Finally,the method of quality cost control and improvement for the construction process is present. The methodology of this paper provides a comprehensive and reliable evaluation for the construction of rock fill dam with face slab based on the real-time quality monitoring system and a scientific support for engineering quality management.
