湛江海湾大桥,主塔墩承台总面积达到1000多m2,承台体积约1万m3。考虑到承台施工将在悬吊过程中完成,并且还将经历多种复杂工况,所以施工难度很大,技术含量较高,必须对施工过程中所面临的最严峻工况进行严格的计算分析,本文主要对塔墩承台封底层的两种最不利工况进行了受力分析。 Zhanjiang Bay Bridge, the total area of ​​the main tower pier cap to reach more than 1,000 m2, cap platform volume of about 10,000 m3. Taking into account the cap construction will be completed in the suspension process, and will also experience a variety of complex conditions, construction is very difficult, high technology, the construction process must be the most severe conditions to be rigorously calculated Analysis, this paper mainly carried out the force analysis of the two most unfavorable conditions of the bottom of the tower pier caps.
