基于AHP的预制构件生产质量影响因素分析

Analysis on production quality influencing factors of prefabricated components based on AHP

与传统的现浇作业相比,装配式建筑是建造方式的重大变革,其建造过程涉及预制构件生产、现场安装等多个环节,对质量管理提出了更高的要求。预制构件作为装配式建筑的主要组成单元,其质量直接影响建筑整体的结构安全和使用功能。为了更有针对性的指导装配式建筑预制构件生产的质量管理,本文通过对装配式预制构件生产全过程进行分析,依据全面质量管理理论对常见质量影响因素等进行归纳总结,并基于层次分析法原理构建质量风险分析模型,采用权重值衡量各因素对构件生产质量的影响大小。结果表明:质量管理组织机构、原材料质量、人员技术水平、模台生产线这4项因素对预制构件生产质量的影响最大,应作为质量管理的重点加以管控。本文成果可为类似项目的质量管理决策提供参考。

Compared with the traditional cast-in-place operation,the prefabricated building is a major change in the construction method,and the construction process involves multiple links such as prefabricated component production and on-site installation,which puts forward higher requirements for quality management.As the main component of the prefabricated building,the quality of prefabricated components directly affects the overall structural safety and use function of the building.In order to guide the quality management of prefabricated building prefabricated components production in a more targeted manner,the whole production process of prefabricated components is analyzed,the common quality influencing factors are summarized according to the total quality management theory,a quality risk analysis model is constructed based on the principle of analytic hierarchy process,and the weight value is used to measure the impact of each factor on the production quality of components.The results show that the four factors of quality management organization,raw material quality,personnel technical level and mold table production line have the greatest impact on the production quality of prefabricated components,and should be controlled as the focus of quality management.The results can provide a reference for quality management decision-making of similar projects.
