T1  - Federal highway A 26 in Germany : reinforced dams in soft soils - control method according DIN 1054
N2  - In 2001 the construction of the Federal Highway A 26 in Lower Saxony (north of Germany) was started. In this area the underground is without any substantial bearing capacity as it consists of soft layers ( clay, peat) with a thickness of up to 12 m. Because it was not possible to exchange the soil neither completely nor partially pre-loading procedure (consolidation method) was chosen for this construction. Short- and long-term stability are ensured by the use of high-tensile fabrics for reinforcement at the dam basis. The vertical and horizontal deformations and the stress changes in the soil, caused by the pre-load procedure, has to be controlled by special geotechnical measurements. Additionally, in the higher parts of the dam the strain behaviour of the high-tensile fabrics is measured. These measurements form the basis for the application of the control method according DIN 1054. In this article, the special circumstances of this project are described. Further on the geotechnical measurements, the winning and evaluation of the necessary parameters of the subsoil, and the consequences of these data for the ongoing of the project are laid down. Intermediate results of the geotechnical measurements are described.
