| 摘 要： | 以广东某斜梁桥为工程背景,探讨了分段施工合成预应力混凝土箱梁桥的特点,并对其受力性能分析研究.计算表明,采用本文提出的分阶段施工合成箱梁方案可保证该大桥在使用荷载组合作用下的受力要求,节省项目投资.对于类似的连续箱梁,当施工吊装能力受限,或现浇施工困难,或无法采用支架施工时,本文提出的思路可供借鉴.

| Abstract: | Based on a cartain bridge in Guangdong province, the characteristic of prestressed concrete compositive box beam bridge with construction by stages is discussed, and the loaded property of this bridge is also analyze. The results showed this bridge can satisfy the demand of accepted load. When the suspended ability is limited, and it is difficult to pour in spots, or the construction method used bracket is impossible, the proposed concept can be consulted. |
