为提高地下结构震害风险判决的科学性和智能化水平，提出一种基于证据理论的地下结构震害风险信息融合方法。在地下结构震害风险智能监测的基础上，根据震害风险融合原理，构建基于智能监测和专家判决的地下结构震害风险融合模型。遵循证据理论的原则和模型规则，构造统一的地下结构震害状态空间和风险概率表达方式，建立风险融合证据框架，确定判决规则，设计风险融合证据模型组件。计算结果表明，该模型能有效提高地下结构震害信息诊断的可信度，充分显示了该融合模型组件的有效性。

To improve the scientific and intelligent peculiarity in the earthquake-damaged risk judgments for underground structure,an earthquake-damaged risk information fusion method is proposed based on evidence theory. On describing the principle of such risk intelligent monitoring structures for underground engineering, the earthquake-damaged risk fusion rule is proposed,and the earthquake-damaged risk fusion model is erected for underground structure on intelligent monitoring and expert judgments. Following the nature ideology and model rule of evidence theory, the uniform status space and risk probability expression mode is established,the fusion frame is built,the decision-making rule is determined,and the fusion model component is designed for the risk evidences about such earthquake-damaged underground structure. Example shows that the model can effectively improve the decision-making credibility about the earthquake-damaged information fusion for underground structure, fully demonstrating the effectiveness of such fusion model component.
