Sicherung 100-jähriger Uferböschungen am Teltowkanal in Berlin

Securing of 100 years old bank slopes at the Teltow Canal in Berlin

The channel Teltowkanal forms part of the waterway system in Berlin and was opened in 1906. In connection with the traffic project "German Unity no. 17" for the development of the waterway between Hannover, Magdeburg and Berlin the Teltowkanal is going to be extended to a water depth of 4.0 m. The contract section of approximately 2.4 km between Tempelhof harbor and the motorway interchange Neukölln shows existing slopes with a special challenge. In this section the channel runs in an insection with unusual high slopes of up to 17 m. During construction of the channel commercial buildings were built along the slope heads with many of them today considered industrial monuments. In many parts of the contract section the analysis of slope stability did not prove safe. Therefore it was required to secure the existing slopes before starting with the bank walls. The following article describes the analysis of slope stability and presents selected construction systems for improving the structural safety.
