[Abstract]:The determination of the weight of multi-source effect in dam monitoring is of great significance to the fusion analysis, reasoning and identification of dam service behavior, and then to the realization of dam safety monitoring. The multi-source effect evaluation system of dam has the characteristics of randomness and uncertainty. Reasonable measurement of the uncertainty of the system is the premise to realize the accurate reasoning of dam service state. Based on the classical rough set theory, on the basis of expounding the shortcomings of the existing research methods and referring to the existing research results, an improved rough entropy model for describing the boundary uncertainty and knowledge uncertainty of dam system set by using roughness and rough entropy is proposed, and the improved rough entropy model of dam system uncertainty measurement is constructed by combining the two organically. Finally, combined with a concrete engineering example, the weighting of multi-source effects in dam monitoring and the reasonable reasoning of dam service behavior are realized, which provides a new idea for the fusion analysis and evaluation of multi-source effects in dam monitoring.
