摘　　要：为加强港口码头安全管理,保证港口码头结构正常运行,通过现场调查观测出高桩码头平台桩基、横梁、帽梁和面板的受损情况。针对码头后平台横梁进行现场载荷试验,测试出后平台横梁在汽车荷载作用下的应变、挠度和裂缝宽度变化等行为,检验码头后平台横梁的抗弯和抗剪承载力是否满足设计要求。结果表明,试验过程中在汽车荷载作用下码头后平台横梁近支座截面最大应变、跨中最大挠度、裂缝宽度变化均在正常范围内,码头平台结构安全性和使用性均满足设计要求。In order to ensure the safety management and normal operation of ports and wharfs,this paper surveys and observes the current state of pile foundation,beams,cap beams and panels of high-piled wharf platform on site,measures the strain,deflection and crack width of rear platform beam of wharf under vehicle load through field loading test,and checks whether the bending and shear bearing capacity of the rear platform beam meet the design requirements or not.The results show that the maximum strain,mid-span maximum deflection and crack width of the support-closer section of the rear platform beam of wharf are all within the normal range,and the security and service ability of wharf platform structure meet the design requirements.
