- Protection of ecologically valuable areas
- Flexible construction for adaptation to inhomogeneous, soft subsoil conditions
- Metrological monitoring of a new construction (vertical/horizontal deformations, earth pressures)
- Usability under extreme dynamic load
003-2005 Geoplastics - Building on soft ground:
- Construction
- 6 layers d = 0.5 m, Front tilt 80°
- sandy gravel
- steep slope 1 geogrid, PES Garne, PE casing; Tmax = 155 kN/m, Tcal =42 kN/m
- steep slope 2 Geokomposit, PP Garne, PP non-woven fabric; Tmax =227 kN/m, Tcal =36 kN/m
- Safety factor for standard calculation η = 1.4
- Experience during operation under direct heavy goods traffic
- Vertical deformations of the entire construction (30 - 50 cm)
- proof load
- 6 anchors, each 15 m long
- loading area 2.0 x 2.5 m
- Measurements: Settlements, horizontal deformations, earth pressures
- Results
- Horizontal deformations < 1.5 - 2.0 mm at σ = 600 kPa
- Test load (limited by anchor load 20 - 25 times higher than calculated
- No fracture condition to be achieved --> load-bearing behaviour considerations required
