摘要
V型墩连续刚构桥具有造型活泼、美观、富有动感的特点,桥梁景观效果较好,结构兼具有梁桥和拱桥的特点,已成为目前比较流行的一种桥型。该文通过对年楚河特大桥主桥上部结构采用(60+148+60)mV形刚构加拱组合结构施工过程中的结构受力状态分析,研究了结构受力的薄弱环节和结构的变形状态,为桥梁在施工中的应力和线形控制提供参考数据。
The V-shaped pier continuous rigid frame bridge has the characteristics of vividness, beauty and fashion, and the landscape effect of the bridge is better. Its structure has the characteristic of beam bridge and arch bridge, and has already become one of the popular types of bridges. The article analyzes the structural stress status in the construction process of the(60+148+60) m V-shaped rigid frame and arch combined structure used for the superstructure of the main bridge of Nianchu Bridge, and studies the weak link of structure stress and the deformation status of structure, which can be referred for the stress and alignment control in the construction of bridges.
