摘要
再生砂粉工程应用有效降低了建筑业碳排放。为了科学有效地进行再生砂粉工程应用的质量管理,在全生命周期理论视角下,采用文献检索、网络问卷与专家访谈相结合的方法对再生砂粉全生命周期的风险因素进行识别并打分,确立了再生砂粉风险评价指标体系。并运用贝叶斯网络模型,构建建筑砂粉全生命周期风险评估模型,得到再生砂粉质量风险因素的发生概率和致因路径,为再生砂粉全生命周期质量管理提供了新的思路和方法。
The engineering application of reclaimed sand powder effectively reduces the carbon emissions of the construction industry.To scientifically and effectively carry out the quality management of the engineering application of recycled sand and powder,this study uses the method of literature retrieval,network questionnaire,and an expert interview to identify and score the risk factors of the whole life cycle of recycled sand and powder from the perspective of the whole life cycle theory.Then,this study establishes the risk assessment index system of recycled sand and powder,and uses Bayesian network model to build the risk assessment model of the whole life cycle of building sand and powder.The occurrence probability and causative path of the quality risk factors of recycled sand powder are obtained,which provides a new idea and method for the whole life cycle quality management of recycled sand powder.
