| 摘要： | Pile- or column-supported walls reinforced with biaxial geogrids are a cost-effective alternative to deep foundation solutions on sites that contain deposits of peat and soft, organic soils. Even with relatively high expected loads, the load transfer platform system with multiple rows of geosynthetic over relatively cost-effective timber piling supported a 19-foot (5.8-m) wall while allowing less than 0.3 psi (2 kPa) of excess pore pressure within the underlying highly deformable deposits. Lateral movements of the wall over its service life were ultimately less than 2 inches (5 cm). Greater pore pressure and lateral movement were recorded as a result of additional pile driving behind the wall than that of the vertical wall load itself. As of this writing, the wall has been deconstructed, the shoo-fly tracks removed, and the new BNSF Bridge over 1-294 is in full operation. |
