Foundation of a bridge over the Danube river in Bratislava (Czechoslovakia) in faulted granitoids
Abstract A new bridge has been constructed over the Danube in Bratislava, supported by 8 piers. With regard to expected good foundation conditions a statically indeterminate construction was designed. The allowable settlement of individual piers ranged between 10 and 15 mm. In foundation pits, situated in the river bed and on the north bank, crush breccia and gouges were found. This made the expected settlement problematic. For that reason pressuremeter tests in foundation ground under pier P3 in the river bed were performed. The pressurementer modulus of jointed granodiorite, crush-breccia, and tectonic clay were calculated. The settlement of the pier, calculated on the basis of these results, was consistent with the permissible value.
