摘　　要：预应力混凝土双T板结构已在工业厂房等结构中得到逐步推广和使用,但相关的设计经验总结却不多。通过钦州7^(#)、8^(#)泊位自动化码头的工程实践,介绍双T板结构在港口工程中维修车间设计应用的关键点以及施工注意事项。结果表明,双T板自身的变截面坡和支座选型对下部结构设计存在较大影响,设计时须予以重视,并注意加强对双T板支承梁的配筋复核,建议国标图集考虑增补跨度24 m以上双T板的结构选型,以便于双T板结构有更多的应用空间。The prestressed concrete double-T plates have been gradually popularized and used in industrial structures,but relevant experience summary on their designs is few.Based on the engineering practice of automated wharfs in Qinzhou 7^(#)and 8^(#)berths,this paper introduces some key issues regarding the design and application of double T plates in the maintenance shop of port engineering and matters needing attention during the construction.The results show that the variable cross-section slop and bearing types of double T plates have a great influence on the design of the lower structure.Therefore,it is necessary to pay attention to the design and recheck the reinforcement of supporting beams under double T plates.Furthermore,it is suggested that the Drawing Collection for National Building Standard Design add details of double T plates with a span of above 24 m,so as to make double T plates widely applied.
