质量剖面下建筑施工项目可靠性测度模型及其应用研究

Quality Reliability Measurement Model of Construction Project and Its Application Research

根据建筑工程质量形成的一般规律,建立了包括10个节点要素的工程项目质量可靠性分析的贝叶斯网络(BN)结构;从铁路建设项目施工现场收集到数据后进行CPT参数学习,获得了完整的BN网络;采用两个典型样本数据对模型进行了检验,针对模型中的主要节点变量进行BN推理和敏感性分析,结果显示模型具有较好的预测功能。

According to the law of construction quality growing,a tennodes Bayesian Network of construction project quality reliability has been established;After collecting the data from railway building project construction scene,the CPT parameter of BN is learned,and the final model of BN is obtained;Two typical samples data are used to test the validation of the model,and BN reasoning and sensitivity analysis are manipulated for the main nodes,the result shows the model has good forecast feature.
