Road Dam B 80, Saxony-Anhalt, Germany

Project description:

Investigation of the external and internal safety of an earth dam as a basis of dimensioning an approx. 20 m high and 600 m long earth dam to be founded on unstable, water saturated ground. The planning of the dam had to consider the flooding of a nearby open pit (Salziger See) and subsequent increase of the groundwater level with associated formation of a seepage water flow in the dam body.

Reason:

  • Deviation of Federal Road B 80

Services:

  • Exploration (drilling, penetration tests, pressure tests)
  • Soil-static calculations of the external and internal stability
  • Investigation on the deformation of the dam and dam footing ground
  • Determination of the seepage flow and dimensioning of the dam foot drainage system

Advantages:

  • Time saving, as the experts’ office was in the vicinity of the construction site
  • Quality assurance by using experienced soil mechanics engineers and accredited soil mechanics engineers
  • Synoptic approach by employing a multidisciplinary team and therefore guaranteeing the success of the project

Additional project data:

  • Height of dam: 20 m
  • Length of dam: 600 m
