珠海大桥除主、副航道桥外均为跨径25m和40m的预应力混凝土简支T粱。其中25mT梁45孔540片，40mT梁34孔408片，所有T梁全部采用预制吊装方案，本文仅对珠海岸预制场的移梁及跨墩龙门的设计与应用作一介绍。1龙门的主要工作任务1．1珠海岸预制场设在该岸引桥的上游侧，垂直于桥轴 Zhuhai Bridge in addition to the main and auxiliary channel bridge are span 25m and 40m of prestressed concrete simply supported T beam. Of which 540 are for 45mT beam, 408 are for 34mT beam, and 408 are for 34mT beam. All T beams are prefabricated. This paper only introduces the design and application of moving girder and transom gantry in prefabricated Zhuhai coast. 1 The main task of the gantry 1.1 Zhuhai coast prefabricated field is located in the upstream side of the bridge approach, perpendicular to the bridge shaft
