MODEL STUDIES OF HYDRAULIC PHENOMENA OCCURRING DURING THE SCOURING OFBRIDGE PIERS /IN POLISH/

THIS ARTICLE DESCRIBES A QUANTITATIVE AND QUALITATIVE LABORATORY STUDY ON MODELS OF SCOURING PHENOMENA. TESTS WERE CONDUCTED ON VARIOUS SHAPES OF PIERS: TRADITIONAL PIERS, COLUMN PIERS, LOZENGE PIERS. RESULTS SHOW THAT THE REMOULDING OF THE RIVER BED VARIES WITH THE SHAPE OF THE PIER CONSIDERABLY; THE TRADITIONAL PIER CAUSES A SWELLING OF THE WATER UP STREAM OF THE BRIDGE AND IMPORTANT WHIRLING MOVEMENTS BEHIND THE PIER; COLUMN PIERS PART THE WATER VERY BRUTALLY CAUSING MAXIMUM SCOUR OF THE RIVER BED, AND LOZENGE PIERS ARE THE LEAST SUSCEPTIBLE TO CAUSE SCOUR AS THEY PART THE WATER PROGRESSIVELY AND RELATIVELY FAR UPSTREAM FROM THE CUTWATER OF THE PIER. THE DEPTH OF THE ERODED HOLE IS PROPORTIONAL TO THE TURBULENCE OF THE WATER ROUND THE BRIDGE PIER. /TRRL/
