基于接力链与质量损益函数的大坝混凝土施工质量控制机理研究

For the quality problems often appeared in dam concrete construction due to the quality control being not in place, based on the theory of relay chain and quality gain-loss function, the relay chain seamless handover mechanism and the optimization calculation model of relay potential are studies, thereby enhancing the efficiency of the transfer process and optimizing the allocation of resources. The multivariate quality gain-loss function model and fuzzy quality gain-loss function are studied, so as to provide theoretical guidance for tolerance design of dam concrete construction. Quality gain-loss transfer model is studied to provide theoretical guidance and technical route support of critical quality source diagnosis and detection for dam concrete construction. By the results of the research, the quality of dam concrete construction can be controlled, the foundation of rapid construction with high quality for concrete dam and the creation of no-crack dam is laid, the quality management theory are enriched.
