【摘要】：“百年大计,质量第一”是我国建筑工程行业一贯坚持的方针。工程质量管理是工程项目各管理工作的重要组成部分,近几十年来,我国建筑行业飞速发展,工程质量水平逐年提高,但各种工程质量事故也随之频繁出现,事故不仅会造成大量的经济损失,还会威胁到人民群众的生命和财产安全,甚至影响社会的稳定,因此,保证工程质量是工程建设中的重中之重。由于工程建设是一个极其复杂的综合过程,它具有生产流动、材料不一、自然条件多变、现场配合复杂等特点,质量影响因素也纷繁复杂,如何准确把控各质量影响因素,确定各影响因素的影响程度,从而有针对性的采取质量控制措施,是保障工程质量的重要路径。论文针对工程质量影响因素的特点,把模糊事故树分析方法运用到工程质量控制中,首先介绍了国内外工程质量控制的发展现状,对工程质量特点、质量影响因素以及质量控制理论进行了分析,其次对模糊事故树理论进行了研究,重点探讨了事故树理论在工程质量控制中的应用并建立事故树模型。最后结合案例,对某一工程混凝土地面裂缝质量问题进行研究,通过层层分析,找出导致事故的直接原因、间接原因以及潜在原因,分析各原因之间的逻辑关系,调查各原因的发生概率,通过事故树模型计算得出原因事件的重要度排序,从而提出更高效的质量控制措施。
[Abstract]:"one hundred years plan, quality first" is a consistent policy of the construction engineering industry in China. Engineering quality management is an important part of the management of engineering projects. In recent decades, the construction industry of our country has developed rapidly. The level of engineering quality has been improved year by year, but all kinds of engineering quality accidents have appeared frequently, which will not only cause a lot of economic losses, but also threaten the safety of people's lives and property, and even affect the stability of society. Ensuring engineering quality is the most important part of engineering construction. Because engineering construction is an extremely complex and comprehensive process, it has the characteristics of production flow, different materials, changeable natural conditions, complex cooperation on the spot, etc. The quality influence factors are also complicated. How to control each quality influence factor accurately and determine the influence degree of each influence factor, so as to take the quality control measures pertinently, This paper applies fuzzy accident tree analysis method to engineering quality control, firstly introduces the development status of engineering quality control at home and abroad. The characteristics of engineering quality, quality influencing factors and quality control theory are analyzed. Secondly, the fuzzy accident tree theory is studied. This paper mainly discusses the application of accident tree theory in engineering quality control and establishes an accident tree model. Finally, combined with a case study, the quality problem of concrete floor cracks in a certain project is studied. Through layer by layer analysis, the direct cause of the accident is found out. The indirect causes and potential causes are analyzed the logical relations among the causes are analyzed the probability of occurrence of each cause is investigated and the order of importance degree of the cause events is calculated by the accident tree model so as to put forward more efficient quality control measures.
