摘要
针对广东某特大桥引桥承台的结构形式及水文气象条件,着重介绍了钢吊箱承重系统的优化设计。实践表明采用牛腿反吊承重梁作为主要承重结构,同时将牛腿镶嵌到封底混凝土中,尽可能提高承重系统的底标高,变水下施工为水上施工,封底混凝土仅作为止水装置的设计,具有非常大的适用性和经济性。
According to the structural styles and hydrological and meteorological conditions of a bridge pile cap in Guangdong,the optimization design and key technology of high pile cap bearing system steel box was introduced in detail. Practice shows that the use of anti-hanging bracket bearing beam as the main load-bearing structure,the bracket was set to cover concrete as far as it possibly improved the bottom elevation of bearing system,construction was changed from underwater to above water,and bottom sealing concrete for the design of the water plant,all of them had large usability and efficiency.
