A certain engineering adopts the scheme of setting closely arranged inclined piles with low permeability at the forefront of the wharf to conform to the flow state of the forefront,which is combined closely arranged inclined piles with high pile wharf structure.To investigate the wave reflection and wave load on the new closely arranged inclined pile wharf structure under different water levels,wave directions,and recurrence periods of wave action,we carry out overall physical model tests of waves to analyze wave elements under different operating conditions.The results show that there are significant differences in wave reflection at different positions in front of the closely arranged inclined piles,with a maximum comprehensive reflection coefficient is 1.45 and a maximum comprehensive transmission coefficient is 0.40.The difference in wave reflection between 90° transverse waves and 25° oblique waves is significant,about 1.22 times.There are gaps between the closely arranged inclined piles and upper wave crossing spaces that dissipate wave energy,and the structural scheme is feasible.The use of this scheme can break the dependence of physical diversion embankments on maritime policies,while reducing the impact on the marine environment and achieving intensive utilization of complex coastlines.
