| Abstract: |
Approximately half of the major bridges (length of more than 250m) along the motorway A 71 and A 73 through the Thuringian Forest were incrementally launched. This is true for reinforced concrete box girder bridges as well as for steel composite bridges. By means of a statistic analysis spans and construction depths are presented and conclusions are drawn for the design and the construction of the bridges. Special features are addressed in particular examples of selected bridges, thereby concentrating on some distinctively German characteristics. |
