摘　　要：针对目前航道护岸结构存在的问题,提出了一种新型直立式生态航道护岸消波结构,该结构可有效减弱水流和船形波对岸边植物的冲刷,并保持水生植物区与行洪通航区的水体连通和生物通行,构建河滨带自然生境,改善航道生态系统。通过对平板格栅型、平直孔洞型、圆柱格栅型3种直立墙体消波构造形式开展试验研究,结果表明:平直孔洞型、平板格栅型和圆柱格栅型消波结构透射系数范围分别为0.15~0.40、0.40~0.60、0.40~0.80,消波能力平直孔洞型>平板格栅型>圆柱格栅型。新型直立式生态航道护岸消波结构可为航道护岸设计提供参考依据。This article proposes a new type of upright ecological waterway revetment and wave dissipation structure to address the existing problems in the current waterway revetment structure.This structure can effectively reduce the erosion of water flow and ship shaped waves on shoreline plants,while maintaining water connectivity and biological passage between aquatic plant areas and flood navigation areas,constructing natural habitats in the riparian zone,and improving the waterway ecosystem.Through experimental research on three types of vertical wall wave dissipation structures,namely flat grid type,flat hole type,and cylindrical grid type,the results show that the transmission coefficients of flat hole type,flat grid type,and cylindrical grid type wave absorption structures are in the range of 0.15-0.40,0.40-0.60,and 0.40-0.80,respectively.The wave absorption capacity from high to low is flat hole type,flat plate grid type,cylindrical grid type.The new upright ecological channel revetment and wave dissipation structure can provide reference basis for the design of channel revetments.
