Calibration of Safety Factors for Piping Failure Mechanism in Levees
The Dutch flood defences are periodically tested against statutory safety standards defined in terms of maximum allowable probability of flooding. As such, a set of tools for assessing the safety of flood defences was developed (project WBI-2017), which includes probabilistic as well as semi-probabilistic assessment procedures. To ensure consistency between probabilistic and semi-probabilistic assessments, safety factors had to be calibrated considering the new models and uncertainties involved. Important aspects for this calibration were the derivation of the safety requirements, the definition of design values, and the handling of spatial correlations and multiple failure mechanisms. This paper presents the framework and outcome of such calibration for the piping failure mechanism in levees. Assumptions and choices to achieve the main objectives of the calibration’s framework are here discussed, with emphasis placed on the safety format. Lastly, an example of the assessment procedure is also presented.
