| Presented is the results of a model study about scouring around a bridge pier. 24 different types of piers were inestigated for the depth and width of scouring. The grain size of sand used in the experiment ranges from 0.149 to 2, 380mm, The time required to reach the stable bed formation was about 30min, with the range of Froud number from 0.58 to 0.69. It has been found that the scouring is most severe at the frontal side of the pier and decreases with decreasing a contact angle (between the center line of the pier and tangent to the frontal face). For design purposes, it is recomanded that the contact angle at the frontal face is 25 degrees for a triangular type and 40 deyrees for a circular type respectively. |
