杭州石大路大桥为一座上承式拱桥,跨径组合为88+160+88m,采用水平转体施工,转体角度26°,转体重量16 800t,在同类型桥梁中其转体重量位居世界第一。该文主要介绍转体施工中上下球铰、滑道、牵引及助推系统等的设计,并对转体施工进行了监控计算。该桥梁的成功转体合龙对以后同类型桥梁的转体施工具有一定的技术指导作用。
Hangzhou Shida Road Bridge is a supporting arch bridge with a combined span of 88 + 160 + 88m. It adopts horizontal swivel construction with a swivel angle of 26 ° and a swivel weight of 16,800t. Its swivel weight ranks the highest among similar types of bridges World number one. This article mainly introduces the design of the upper and lower ball hinges, slideways, traction and boosting systems in swivel construction, and carries out the monitoring and calculation of swivel construction. The success of the bridge of the swivel the same type of bridge after the swivel construction has a certain technical guidance.
