- Simple or Global check:
- Global check according to VTV (i.e. step 1 till 5 of VTV-2006)
- Simple check according to CUR-113
- Detailed check (as described in the report "Technische Rapport ...")
- Advanced check (using the existing program SLIQ2D)
1. Global check (VTV-2006)
1.1 Check on liquefaction (steps 1 t/m 5 described in VTV-2006)
xxx
Figure 1: Checking schema for liquefaction
...
Step 1 - Geometrical check: damaging criterium liquefaction
The damaging criterion is met if at the so-called assessment level is situated within the slope (i.e. on landward side of) the so-called observation profile, in accordance with Annex 9.4 of the VTV-2006.
...
2. Determination of the assessment level
3. Comparison of the observation profile with the existing profile
X Ssign = X co-ordinaat of the observation profile from the foreshore
X SZV = X co-ordinaat of the liquefaction point from the foreshore
Step 2: Artificially underwater installed and non-compacted sandy foreshore?
Step 3: Is the dumping criterion satisfy?
Directly in front of the toe of the dike or on the outside of the toedumping or to the outward end of a dumping, the slope 1:2.5 may not be cut by the profile.
Step 4: Liquefaction is possible on the basis of geometry?
The occurrence of a liquefaction is possible if one of the two following conditions is met:
- The average slope is steeper than or equal to 1:4, over a height of at least 5 m;
- The total slope (channel edge-channel bottom) is on average steeper than or equal to 1:7.
Step 5: Are there any sensitive to liquefaction layers present?
2. Simple check according to CUR-113
...
- Is er voldoende grondonderzoek (boringen op ten hoogste 500 m tot 1 km afstand tot een diepte van de teen van het talud om de korreldiameter te bepalen)? Indien ja ga door naar 3, indien nee geen toetsing mogelijk.
- Beschouw de korrelverdeling van het zand op basis van de boringen
- is het zand niet te fijn d.w.z. is de over lagen van ten hoogste 5 m gemiddelde korreldiameter d50 van het zand overal dus over de gehele taludhoogte tenminste 200 μm en d15 tenminste 100 μm? Indien nee, zeer fijn zand: gedetailleerde analyse bresvloeiing nodig (bijv. met HMBreach). indien ja ga naar 3 b.
- is het zand tamelijk grof d.w.z. is de over lagen van ten hoogste 5 m gemiddelde korreldiameter d50 van het zand over de gehele taludhoogte tenminste 500 μm en d15 tenminste 250 μm? indien ja, tamelijk grof zand of grind ga naar 4 a anders niet te fijn zand ga naar 4 b.
- beschouw de geometrie van het talud. zijn er delen van het talud met een hoogte als gegeven in de eerste kolom van de tabel gelijk of steiler dan gegeven in de tweede kolom? Zo ja dan is het talud bresgevoelig, ga naar 5 zo nee GOEDGEKEURD. Voor taludhoogtes van meer dan 40 m is een gedetailleerde analyse nodig.
- tamelijk grof zand d50 > 500 μm en d15 > 250 μm:

- De verwachte maximale inscharingslengte ten gevolge van een bresvloeiing bedraagt 2 tot 3x de taludhoogte (dit geldt voor zandwinputten in het rivierengebied, in Zeeland en Waddenzee veiligheidshalve uitgaan van 7.5x). Indien de afstand van de top van het bresgevoelige talud tot de teen van de waterkering kleiner is dan 2x de hoogte van het bresgevoelige talud dan wordt de situatie AFGEKEURD. Door aanbrengen van bestorting of bekleding op de (onderwater-) oever kan de inscharingslengte beperkt worden.
