Comparison between results of static pile load testing, PDA results and calculated bearing capacities for pile design on the bridge over river Drava

摘要

On the Corridor Vc in the Republic of Croatia, bridge over the river Drava has been designed The Corridor Vc is a part of the TEM network infrastructure of Southeastern Europe, passing from Budapest (Hungary), through Osijek (Croatia), Sarajevo (B&H), up to the Port of Ploce (Croatia) Bridge over the river Drava is 2485 m long The bridge is designed like cable-stayed bridge, with 100 +220 +100 long spans, and concrete semi-prefabricated structure on the river banks (approximately 35 m long spans) The heights of the pylons are 75 m All piers are placed on Φ150 cm, 19, 22, 25 and 30 m long bored piles, in layers of uniform graduated loose to medium dense sands In the design stage four static pile load tests have been performed PDA tests were performed on same piles Additional 40 PDA tests will be performed on piles in the construction of the bridge Comparison between results of static pile load tests with PDA results and comparison with the calculated bearing capacities will be shown in this paper (Reese and O'Neill - β method, calculation of pile bearing capacities from CPTU tests).
