This section describes a number of benchmarks for which an exact analytical solution can be found in the literature.
1.1. Study Case described in "Technisch Rapport Voorland Zettingsvloeiing"
Description
The example given in "Annex A - Case Study" of the Deltares report 1200503-001-GEO-0004 "Concept Technisch Rapport Voorland Zettingsvloeiing" of G.A. van den Ham & Co is used.
In this example, both global and detailed checks are completed on the basis of a (fictitious) dike section, which with regard to geometry and soil structure is typical of the Southwest Delta.
The dike has a height of NAP+5 m and a crest width of 3 m.
The foreshore begins to imaginary toe of the dike at an elevation of NAP and is 60 m wide. The toe of the trench is NAP-15 m and has a slope of 1:6. The dike section is 800 m long.
The soil profile is as follows:
...
This section uses the results of a by-hand calculation performed for three profiles of the Spui dike project (see figure below):
- hmp km 63.9 (Nieuw Beijerland)
- hmp km 65.0 (between Oud Beijerland and Nieuw Beijerland)
- hmp km 67.8 (oud Beijerland)
XXX Insert figure
As the details of the calculation performed by hand are not available, those benchmarks are set in group 2.
