Description

A: Tightening safety format (damage factor, material factor, model factor) based on probability of failure analyses and area characteristics. B. Model adjustments Uplift Van This essentially concerns a difference analysis of the results with the same model input of stability sums in different versions of the model software (D-Geo Stability and D-Stability) of Deltares on the basis of which the (calculation) model factor can be tightened. C. Application Direct Simple Shear (DSS) tests for peat A: Tightening safety format (damage factor, material factor, model factor) based on probability of failure analyses and area characteristics. Deltares has previously also been the only one to tighten up the safety format for the Rivierenland Water Authority in a similar way, under the guidance of their expert advisor. This makes Deltares the only party on the market with experience in this field. B. Model adjustments Uplift Van This essentially concerns a difference analysis of the results with the same model input of stability sums in different versions of the model software (D-Geo Stability and D-Stability) of Deltares on the basis of which the (calculation) model factor can be tightened. As the developer of the software, Deltares is the only party with sufficient knowledge to perform this comparison. No research has previously been conducted into the impact of the Uplift Van model adjustment on the required calculation model factor. This is new research. The knowledge and expertise for this work is only available at Deltares. C. Application Direct Simple Shear (DSS) tests for peat In the tightening of the safety format at the Rivierenland Water Authority, research was also carried out at the time into the strength parameters of peat on the basis of DSS tests. Because of the possible link with part A, it is efficient, efficient and cost-saving to invest this with the same party and to make it part of the same research.
