Abstract

One of the most frequent probable reasons for bridge pile foundation collapse, scouring can result in fatalities as well as economic and environmental consequences. However, in the local scour simulation, there are few thorough numerical investigations around pile groups consisting of front, middle, and rear piles with various inclination degrees of flow attack. The maximum depth of local scour and its mechanism surrounding groups of four cylinders with various arrangements of inclining angles were determined by numerical simulation using Flow-3D software. A validation using the experimental investigation as a comparison was carried out to verify the numerical model. Compared with experimental results, good conformity is shown in the numerical results of scour depth and bed elevation contour using the Van Rijn transport rate equation and RNG k-ε turbulence model. Numerical simulations of four cylinders in different alignment angles were carried out with pile spacing ratios, G/D of 2.5, 3, and 3.5. The deepest maximum local scour always obtained at the rear pile. The trend of maximum local scour depth is consistent with experimental studies, which demonstrated the reliability and capability of the numerical model used to simulate pile groups in estimating sediment scour depth.
