摘　　要：由于复合桩基础的经济性,近年来受到越来越多的关注,但在航道护岸工程中应用较少,究其原因是航道护岸低桩承台复合桩基础受力更加复杂、技术上较难把握。通过分析航道护岸低桩承台复合桩基础竖向承载力和水平承载力,提出了复合桩基础设计控制原则:1)竖向整体安全度K≥2,地基承载力利用率ψ≥0.5。2)桩土联合承担水平力。制定了航道护岸复合桩基础的设计方法及流程,为类似工程提供参考。Due to the economics of composite pile foundations,it has received more and more attention in recent years,but it has been less used in waterway revetment projects.The reason is that the force of composite pile foundations with low pile caps on waterway revetments is more complicated and technically difficult.By analyzing the vertical bearing capacity and horizontal bearing capacity of the composite pile foundation of low pile caps retaining wall of waterway revetments,the design control principle of the composite pile foundation is proposed:1)Vertical overall safety K≥2,fulfilled rate of subsoil bearing capacityψ≥0.5.2)Pile and soil jointly bear horizontal force.The design method and procedures of the composite pile foundation of waterway revetments is formulated to provide a reference for similar projects.
