Bayesian Belief Nets

Application of the Bayesian Belief Nets in dam safety monitoring The systems for earth dam monitoring should enable measurements of basic physical parameters describing the behavior of the structure, including: soil water pressure, soil stress, displacements, leaks, and drainage discharges. In the case of earth dam safety assessment, the monitoring data are used to detect any anomalies in dam behavior. In this paper, the dam safety has been analyzed using the Bayesian Nets. Two types of information: water pressure measurements and drainage discharge measurements are used in analyses. The seepage anomalies in the Klimkówka Dam were considered in demonstrate the practical advantages of using the Bayesian Nets for monitoring data interpretation. Presented examples of the Bayesian Nets applications (forward and backward propagation) in analysis of seepage through earth dams show that this method can be an effective tool supporting an assessment of dams technical condition and monitoring of the dam safety.

Qualitative Index

Since there are few methods to evaluate the qualitative index in dam safety monitoring and the evaluation system is imperfect, in this paper a new quantitative and comprehensive evaluation method for qualitative index is explored with the introduction of the method of interval marking, Set-Valued Statistics, grey theory and Jousselme distance function. Firstly, the interval marking method and Set-Valued Statistics are used to obtain the comprehensive quantitative value; then the evaluation class of the comprehensive quantitative value is quantified and the evidence vector is obtained through grey theory; next the weights of all qualitative indices are obtained through Jousselme distance function; finally the comprehensive influence of the qualitative indices on dam safety is determined by using the evidence vector and weights. The case study proves that this method is feasible which can reasonably determine the influence of qualitative index on dam safety.
