基于过程能力指数的施工工序质量控制研究

摘要

为丰富建筑工程质量过程能力的研究,解决建筑工程中的实际问题,将过程能力指数引入屋面防水工程的质量控制。根据建筑施工过程的特性,采用校正过程能力指数Cpk,估计屋面防水工程的总体质量水平。工程实例分析结果表明,借助过程能力指数能够适时了解分项工程的整体状态,及时发现施工质量问题与隐患,并可有针对性地加强管理,予以解决。过程能力指数Cpk计算方便,用于建设工程质量的控制具有实际意义。%In order to enrich study on quality process capability and solve practical problems of con-struction engineering,process capability indices was introduced into the quality control of waterproof engi-neering.According to the characteristics of construction process,Cpk was used to estimate the overall quali-ty level of the waterproof engineering.The case study results show that the whole state of the sub-proj ect can be known timely with the process capability indices,and the construction quality problems and hidden dangers can be found and solved correspondingly.The process capability index Cpk is convenient to calcu-late,and it is of practical significance for the construction quality control.
