Group 3: Benchmarks from spreadsheets
This section uses tests performed by hand or by means of an Excel spreadsheet.
3.1 Global check with all possible trajectories
Description
This benchmark tests all possible trajectories according to the Global check. Those trajectories are:
- Case A: step 1 = No → Global check passed
- Case B: step 1 = Yes, step 2 = No, step 4 = No → Global check passed
- Case C: step 1 = Yes, step 2 = No, step 4 = Yes, step 5 = No → Global check passed
- Case D: step 1 = Yes, step 2 = No, step 4 = Yes, step 5 = Yes → Global check failed
- Case E: step 1 = Yes, step 2 = Yes → Global check failed
For case A, the same geometry as benchmark 1-1 (see [group 1]) is used but a different soil profile.
Benchmarks results
Hereafter are given the analytical results per case.
Case A:
Channel depth: H = 15 m
Thickness of the sensitive layer: Hvw = 13 m
Marge = 2 Hvw + 1.5 (H - Hvw) = xxx m
Assessment level: Z = xxx m
XSsign = xxx m
XSzv = xxx m
