Grey comprehensive evaluation of embankment safety based on interval number decision matrix
As an important water conservancy facility to resist flooding, embankment project has the risk of failure due to its complex structure and large variability of operating conditions. This paper establishes a single-objective, multi-level, semi-structural evaluation index system based on the inverse diffusion of consequences method, which comprehensively considers various failure forms of embankments; and constructs a comprehensive evaluation method for embankment safety, which determines the subjective and objective weights of evaluation indexes by introducing interval number theory, combining hierarchical analysis method and entropy value method, scoring intervals based on set value statistics, and finally carrying out comprehensive gray evaluation based on improved hybrid centroid-type triangular whitening function, and on this basis, a Monte Carlo mathematical model is established for the sensitivity analysis of indicators. The safety evaluation was carried out with Wuhan Yangtze River embankment as an example, and the result shows that the integrated evaluation method of embankment safety based on interval number decision matrix has good practicality and more adequate data mining, which can truly reflect the embankment safety condition and has strong engineering guidance significance.
