摘　　要：为加强港区码头安全管理,通过现场静力荷载试验,测试已经出现裂缝的面板在试验荷载作用下的应变、挠度和裂缝宽度变化等行为,检验面板受弯、受剪等承载能力是否满足设计要求,评估面板的安全性和使用性。结果表明:试验过程中码头面板近支座截面最大应变、面板跨中最大挠度、面板裂缝宽度变化均在正常范围内,码头面板存在的收缩变形型裂缝对面板承载力影响不大,面板承载力和安全性满足设计要求。In order to strengthen the safety management of wharves in the port area,through the static load test on site,this paper tests the changes of strain,deflection and crack width of cracked slabs under the test load to verify whether the bending and shearing bearing capacities of the slabs meet the design requirements,and evaluate the safety and usability of the slabs.The results show that the maximum strain of the slab near support section,the maximum deflection within the slab span and the change of the crack width of the slab are all within the normal range during the test;the shrinkage and deformation cracks in the wharf slab have little influence on the bearing capacity of the slab;and the bearing capacity and safety of the slab meet the design requirements.
