研究目的：根据国务院《质量发展纲要(2011 -2020年）％要求，为完善政府质量状况分析及报告制度，探 讨铁路建设工程质量形势评估方案，为铁路行业监管部门质量监督管理提供支持服务。 研究结论：( 1)铁路建设工程质量形势反映的不是具体工程项目质量验收结果，而是众多在建项目质量 受控状态和管控能力水平，反映的是整个行业某个年度或者建设时期的质量整体状况;（2)从数据信息可获 得性、真实性等角度，建议铁路建设工程质量形势评估选择质量监督机构的数据信息作为基础数据，评估指标 可以包括质量行为问题、实体质量问题、质量事故等三个一级指标，并根据建设主体、专业工程和事故分类扩 展确定二级指标和三级指标;（3)基于监督数据的质量形势评估可以采用静态评估方法进行，建议采取评价 打分方法，由质量监督机构或者其委托的咨询机构针对选定的在建工程和参建主体进行综合检查评价，按照 在建项目得分率统计全行业整体状况;（4)基于监督数据的质量形势评估还可以进行动态评估，通过编制铁 路工程质量动态指数反映铁路建设工程整体质量状况在不同时间周期的连续变化，实现对铁路工程质量整 体状况的综合反映和监测;（5)本研究成果主要应用在建设工程管理领域，可为铁路行业监管部门工程质量 监督管理提供辅助决策支持。

Research purposes： According to Quality Development Outline (2011 -2020) of State Government，in order to improve the evaluation system of quality situation by government sector，evaluation solution about quality situation of railway construction industry is discussed for decision aids of railway industry supervision agency . Research conclusions：( 1) Quality situation of railway construction industry^ shows not for any specific projects result， but the whole quality level and status of all under - building projects. It shows the quality situation of railway construction industry during appointed year or period. (2) Based on the factor of truth and availability，the data from governmental quality supervision agency should be used for situation evaluation. The 3 first level indexes can be set for 11 quality behavior problems"，M engineering entity^ quality^ problems"，11 quality^ accidents"，and the second and third level indexes can be choose according to classification of enterprise，professional engineering and accident grade. (3) Static evaluation method can be designed to analyze quality situation of railway construction industry by weighted scoring. Governmental quality supervision agency or otlier consulting company can inspect typical projects and judge the whole industry quality situation by the statistic scoring average. (4) Dynamic evaluation metliod can be designed to analyze quality^ situation of railway construction industry by dynamic index, which can reflect the continuous change during the different time period. (5) The research result can be applied in construction management field, and can be used for decision aids of governmental quality supervision agency.
