【Abstract】 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 earthquakedamaged 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.更多还原
