摘　　要：某工程采用在码头前沿设置低透空率密排斜桩方案归顺前沿流态,即密排斜桩与高桩码头结构相结合。为了探究不同水位、不同波向及重现期波浪作用下,新型密排斜桩码头结构的波浪反射及其受到的波浪荷载情况,通过开展波浪整体物理模型试验对不同工况波浪要素进行分析。结果表明:密排斜桩前方不同位置的波浪反射情况差异显著,综合反射系数最大值为1.45,综合透射系数最大值为0.40;90°横浪与25°斜向浪波浪反射作用差异明显,约为1.22倍。密排斜桩间有缝隙及上部越浪空间对波浪能量起到消散作用,结构方案可行。该方案的使用可打破实体导流堤对于用海政策的依赖,同时减少对海洋环境的影响,实现复杂海岸线的集约利用。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.
