根据结构工程质量形成的一般规律，探索施工系统质量绩效的测度方法，建立了包含9个节点要素的贝叶斯网络模型；从铁路建设施工现场收集到数据后进行贝叶斯网络参数学习，获得完整的BN网络；采用两个典型样本数据对模型进行了检验，实验结果显示模型具有较好的预测功能；文章最后还对模型进行了应用推理和敏感性分析，并给出了若干建议。

According to the law of engineering quality growing, a nine-nodes Bayesian Network of building construction system quality performance has been established; After collecting the data from railway building 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, the result shows the model has good forecast feature；BN sensitivity analysis and reasoning are manipulated, and some pieces of advice are given at last.
