摘要: |
大坝安全监测资料中不可避免地存在误差信息,准确诊断监测资料的合理性对掌握大坝安全性态具有重要影响.在对大坝安全监测资料数据特征分析的基础上,结合多源信息融合技术,构建了数值融合→特征融合→决策融合的信息合理性分析诊断的3级模式,并对大坝安全监测资料合理性诊断各级融合的典型实现方法进行了研究,由此给出了大坝安全监测资料合理性诊断的体系架构. |

Abstract: |
The deviations exist in dam safe monitoring data inevitably. Whether it is reasonable has a significant impact on the accuracy of analysis and diagnosis of dam safety situation. On the basis of data characteristics analysis, the multiple-source information fusion technology is introduced to construct a 3-level analysis model of information rationality that is from numerical-fusion to characteristics-fusion and then to decision-fusion. Then typical methods of each level are given, and from which the system structure is made up for dam safety monitoring data rationality analysis in this study. |
Key words: dam monitoring data rationality multiple source information fusion |
